CCPII-2019-33-4358r1_i 30.05.19 4

Agenda Item 1.3: to consider possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 (WRC-15)

BACKGROUND The meteorological-satellite service (MetSat) and Earth exploration satellite service (EESS) use Data Collection Systems (DCS), which consist in a network of sensors that are critical to monitor and predict climate change, monitor oceans and water resources, predict the weather, assist in biodiversity protection, and improve marine safety in areas that are hard to reach. In particular, the utility of DCS helps the scientific community to gain a better monitoring and understanding of the environment, and to help the industry to comply with the environmental protection regulations implemented by some governments. The frequency band 460-470 MHz is allocated on a primary basis to the fixed and mobile services. It is also allocated on a secondary basis to the MetSat (space-to-Earth) service. Moreover, in some countries of Regions 1 and 3, primary allocation is allowed by No. 5.290 of the Radio Regulations (RR). The operation of EESS applications is also permitted under RR No. 5.289 considering a no-interference and no-protection basis. In addition, channels in the 467.525-467.825 MHz segment can be used for on-board maritime communications under RR No. 5.287 and No. 5.288. Primary allocation to MetSat and EESS services in the frequency band 460-470 MHz may give confidence to the public sector and to space and meteorological agencies on the development of data collection systems and programs, as well as provide regulatory certainty. Therefore, parties interested in using the MetSat and EESS services are seeking to upgrade the MetSat allocation to primary status, and to include a primary allocation to EESS in the frequency band 460-470 MHz while providing protection and not imposing additional constraints on existing terrestrial services nor adjacent frequency bands. Studies have demonstrated that sharing is possible between meteorological-satellite (space-to-Earth)/earth-exploration-satellite (space-to-Earth) services and the incumbent services in the 460 – 470 MHz frequency band if the pfd limits proposed below are applied. Based on the results of sharing studies, this proposal supports an allocation upgrade from secondary to a primary for the meteorological-satellite service (space-to-Earth) and a new primary allocation to the earth-exploration-satellite (space-to-Earth) service in the frequency band 460 – 470 MHz band. This proposal applies a set of elevation angle dependent pfd limits to the meteorological-satellite and earth exploration-satellite services to protect the incumbent services globally.

AGENDA ITEM 1.5

(Item on the Agenda: 3.1 (SGT3))

(Document submitted by CITEL Member States) SGT-3 – Satellite regulatory Coordinator: Brandon MITCHELL - USA

CCPII-2019-33-4358r1_i 30.05.19 13

Agenda item 1.5 of WRC-19: to consider the use of the frequency bands 17.7-19.7 GHz (space-to-Earth) and 27.5-29.5 GHz (Earth-to-space) by earth stations in motion communicating with geostationary space stations in the fixed-satellite service and take appropriate action, in accordance with Resolution 158 (WRC-15); Background Earth stations in motion (ESIM) currently serve a wide range of applications, both on board aircraft and ships and on land and, considering that users expect to be able to connect wherever they are, the broadband service satellite is a key component in meeting that demand.

The 2015 World Radiocommunication Conference (WRC-15) adopted Note No. 5.527A, through which the operation of ESIMs that communicate with geostationary satellite (GSO) networks of the Fixed Satellite Service (SFS) in the frequency bands 29.5-30.0 GHz (Earth-to-space) and 19.7-20.2 GHz (space-to-Earth) under Resolution 156.

However, recognizing the growing demand for mobile services and the global availability of satellite broadband, WRC-2015 adopted WRC-19 Agenda Item 1.5 to consider ESIM operation in the frequency bands 27.5-29.5 GHz (Earth-to-space) and 17.7-19.7 GHz (space-to-Earth) of the FSS, thereby using more spectrum to meet the ESIM demand.

Results of the ITU Radiocommunication Sector (ITU-R)

The bands 17.7-19.7 GHz and 27.5-29.5 GHz are currently allocated to the FSS, among other services, and used by GSO Satellite FSS networks. These bands are shared with other services, including (in some sub-bands) non-geostationary orbital satellite (non-GSO) satellite FSS systems, feeder links for non-GSO systems for the mobile-satellite service and terrestrial systems.

To protect other services assigned in these bands, different use conditions must be applied to the different types of ESIM, since scenarios of interference from other services will be different for maritime, aeronautical and terrestrial ESIM.

The results of the sharing studies on the ESIM and the existing services in the frequency bands 17.7-19.7 GHz and 27.5-29.5 GHz are described below:

The ITU-R reviewed the sharing conditions for ESIM with terrestrial services in the band 17.7-19.7 GHz and concluded that terrestrial service transmitters could potentially interfere with ESIM receivers. Therefore, ESIM should operate under the condition of not claiming protection from terrestrial services operating in accordance with the RR.

In the case of the frequency band 27.5-29.5 GHz, the ITU-R reviewed the sharing conditions for ESIM with terrestrial services in the band 27.5-29.5 GHz and concluded that ESIM transmitters could interfere with terrestrial service receivers. Therefore, aeronautical and maritime ESIM must operate under specific technical, operational and regulatory conditions to avoid causing unacceptable interference to receiving stations of terrestrial services and, likewise, land ESIM need to operate under the condition of not causing unacceptable interference to receiving stations of terrestrial services operating in accordance with the RR.

Results of sharing studies with the Earth Exploration Satellite Service (EESS) (passive)

The ITU-R examined sharing conditions for ESIM with the EESS (passive) in the 18.6-18.8 GHz band used by the EESS (passive) in remote sensing for Earth exploration, in which the EESS (passive) earth station and the ESIM are receiving. Therefore, ESIM receivers can cause no interference with the SETS receiver (passive). The ITU-R noted that the use of ESIM in the band 27.5-29.5 GHz would not change the current interference environment with respect to the secondary service EESS in the range 28.5-29.5 GHz.

CCPII-2019-33-4358r1_i 30.05.19 14

Results of sharing studies with the meteorological satellite service

The ITU-R examined sharing conditions for ESIM receivers and the meteorological-satellite service in the 18 GHz range. The satellite meteorological earth station and the ESIM are receiving in this band. Therefore, ESIM receivers cannot cause interference with the receiving station of the meteorological satellite.

Results of sharing studies with the FSS

The ITU-R reviewed the sharing conditions between the ESIM and the GSO FSS satellite systems in the frequency bands 17.7-19.7 GHz and 27.5-29.5 GHz. As a result, it found that ESIM operations need to be maintained within the envelope of the satellite network with which they communicate, and concluded that to prevent interference between ESIMs and the GSO systems of the SFS of other administrations, the provisions of the proposed Resolution must be followed.

On the other hand, in the bands 17.7-18.6 GHz and 18.8-19.3 GHz, interference from ESIMs with earth stations communicating with non-GSO FSS systems is not anticipated, since both are in the receiving direction (space-to-Earth).

Regarding interferences that ESIM could receive, in the 17.7-18.6 GHz band ESIMs will not claim protection from non-GSO systems, but will accept the levels of protection from non-GSO FSS systems that comply with those established within the pfd limits of Article 22 and, for the band 18.8-19.3 GHz, will operate under the technical and operating parameters contained in the respective coordination agreement in application of RR Nos. 9.12A and 9.13, so ESIM would not require any additional protection.

For the frequency segments 27.5-28.6 GHz and 28.6-29.1 GHz, it was found that the ESIM transmission link could potentially interfere with non-GSO system receivers, and it is proposed that the ESIM protect non-GSO systems as set out in the proposed resolution.

Results of sharing studies with the BSS

ESIM terminals are receiving and BSS feeder link earth stations transmitting in the 17.7-18.1 and 18.1-18.4 GHz bands. Therefore, ESIM should not claim protection or impose restrictions on the development of BSS earth stations.

With respect to the band 27.5-29.5 GHz, ESIMs must remain within the envelope of the satellite network with which they communicate, and it is necessary to indicate this in a proposed resolution contained in the draft text of the CPM.

ADD DIAP/1.5/5

DRAFT NEW RESOLUTION [AI1.5] (WRC-19)

Use of the frequency bands 17.7-19.7 GHz and 27.5-29.5 GHz by earth stations in motion (ESIM) communicating with geostationary space stations

in the fixed-satellite service


considering

a) that there is a need for global broadband mobile-satellite communications, and that some of this need could be met by allowing earth stations in motion (ESIM) to communicate with space stations of

CCPII-2019-33-4358r1_i 30.05.19 18

geostationary-satellite orbit (GSO) fixed-satellite service (FSS) operating in the frequency bands 17.7-19.7 GHz (space-to-Earth) and 27.5-29.5 GHz (Earth-to-space);

b) that appropriate regulatory and interference management mechanisms are necessary for the operation of ESIM;

c) that the frequency bands 17.7-19.7 GHz (space-to-Earth) and 27.5-29.5 GHz (Earth-to-space) are also allocated to terrestrial and space services used by a variety of different systems and these existing services and their future development need to be protected from the operation of ESIM,

Option (MEX): d) that ITU-R has studied whether aeronautical ESIMs are capable of operating without causing harmful interference to non-GSO mobile satellite service feeder link satellite receivers in the band 29.1-29.5 GHz.

DRAFT INTER-AMERCIAN PROPOSAL (DIAP) FOR WRC-19

AGENDA ITEM 1.6


(Document submitted by CITEL Member States) SGT-3 – Satellite services Coordinator: Brandon MITCHELL – USA Alternate Coordinator: Juan MASCIOTRA – ARG; Chantal BEAUMIER - CAN Rapporteur Agenda Item: Marcella OST - CAN Alternate Rapporteur Agenda Item: Carolina DAZA – COL

CCPII-2019-33-4358r1_i 30.05.19 29

Agenda Item 1.6: to consider the development of a regulatory framework for non-GSO FSS satellite systems that may operate in the frequency bands 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space), in accordance with Resolution 159 (WRC-15); BACKGROUND INFORMATION:

Article 22 of the Radio Regulations contains provisions to ensure compatibility of non-GSO FSS operations with GSO networks for the 14/11 GHz and 30/20 GHz bands. Among these provisions are uplink and downlink equivalent power flux density (epfd↑ and epfd↓) limits to protect GSO networks from unacceptable interference pursuant to RR No. 22.2. There are currently no defined technical provisions for sharing between non-GSO systems and GSO networks in the 50/40 GHz frequency bands. Moreover, there are no existing mechanisms in the RR establishing coordination procedures applicable to non-GSO systems operating within the FSS allocations in frequency bands in the 37.5 to 51.4 GHz range, such as application of RR No. 9.12.

To address these issues, and the uncertainty they create among potential operators of non-GSO FSS satellite systems in this 50/40 GHz range, WRC-15 established agenda item 1.6 and associated Resolution 159 (WRC-15) for WRC-19. Resolution 159 (WRC-15) discusses the development of new technologies in the Fixed Satellite Service (FSS) in frequency bands above 30 GHz that would allow for the provision of high-capacity and low-cost communications in all parts of the world, especially in remote and isolated areas. This Resolution considers that satellite constellations in both geostationary-satellite orbits (GSO) and non-geostationary-satellite orbits (NGSO) would allow for the implementation of these new technologies in the FSS bands and that the Radio Regulations should enable the introduction of such technologies to ensure efficient use of the radio spectrum. Resolution 159 (WRC-15) resolves to invite the ITU-R to conduct and complete in time for WRC-19 studies on the regulatory provisions to enable the operation of NGSO FSS satellite systems in the above mentioned frequency bands, including sharing studies with GSO, EESS, and RAS.

CCPII-2019-33-4358r1_i 30.05.19 30

The proposals below present a regulatory solution for providing certainty and technical provisions to allow for sharing between non-GSO FSS systems and for protection of co-frequency GSO networks and adjacent-band EESS (passive) systems under WRC-19 AI 1.6. The proposals have been developed based on the results of ITU-R studies called for in Resolution 159 (WRC-15), and identify a methodology to allow for maximum spectrum efficiency for non-GSO FSS systems, while protecting operations of GSO networks from operations of non-GSO FSS systems. This proposal also provides a regulatory solution to ensure that aggregate emissions from operating non-GSO FSS systems do not exceed aggregate protection requirements of GSO networks. Regarding the protection of GSO systems, CITEL supports the following approach of defining in the Radio Regulations: a) a maximum value for the time allowance for degradation exceeding the minimum short-term performance objectives, in terms of C/N, of a set of GSO reference links due to the interference caused by a single non-geostationary system, as well as the aggregate value for all NGSO FSS systems; and b) a maximum value for the decrease in the time-averaged throughput (spectral efficiency) caused by a single non-GSO system, as well as the aggregate value for all NGSO FSS systems, into a set of GSO reference links using adaptive coding and modulation. For sharing between NGSO systems: Studies on sharing conditions between non-GSO FSS systems operating in the frequency bands 37.5-42.5 GHz (space-to-Earth) and 47.2-48.9 GHz (limited to feeder links only), 48.9-50.2 GHz and 50.4-51.4 GHz (all Earth-to-space) have shown the possible effectiveness of mitigation techniques such as orbital angle avoidance and earth station site diversity in assisting NGSO operators to achieve compatibility between the non-GSO FSS systems studied. To address sharing considerations between NGSO systems, that the use of the bands 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space) by non-GSO FSS systems should be subject to coordination procedures under No. 9.12. In order to provide additional guidance on the coordination of non-GSO systems, and ensure the efficient use of spectrum and orbital resources, that an ITU-R Recommendation could be further developed, which would, inter alia, address the criteria to adequately protect a non-GSO system from the interference caused by all other non-GSO systems operating co-frequency.

USA

Regarding protections of EESS (passive) and modifications to Resolution 750 (Rev. WRC-15), this proposal specifically proposes changes to both GSO and NGSO FSS earth station out of band emission limits as studies have shown that GSO FSS systems alone cause exceedance to the EESS (passive) protection criteria and that in order to allow the aggregate interference from both GSO and NGSO FSS earth stations emission to meet this criteria modifications to both limits are needed. This proposal tracks closely with Method A of Issue 1 and Option B of Issue 2 in the draft CPM Report, leaving the specific values for GSO and NGSO systems as TBD for further analysis. Since recognizing i) of Resolution 159 (WRC-15 ) states that potential revisions to the protection of passive services will be impractical to apply to GSO FSS networks that are operational, planned for near term operation or filed, the proposed changes would not apply to any GSO systems whose complete notification information was received by the bureau before [January 1, 2020].

CCPII-2019-33-4358r1_i 30.05.19 31

Canada: For the protection of EESS (passive) systems: For the band 36-37 GHz: Canada is of the view that based on the results of studies, EESS (passive) systems operating in the 36- 37 GHz band and non-GSO FSS systems are compatible and no regulatory measures are required to address the compatibility between these two services. For the band 50.2-50.4 GHz: Canada is of the view that based on the results of studies, regulatory measures such as revising the current unwanted emission limits in Resolution 750 (WRC-15) are required to ensure compatibility between EESS (passive) systems operating in the band 50.2-50.4 GHz and non-GSO FSS systems, but has not yet decided on appropriate values.

Mexico

For the protection of EESS (passive) systems in the band 50.2-50.4 GHz, Mexico is of the view that the current unwanted emission limits in Resolution 750 (WRC-15) are required to be revised to ensure compatibility between EESS (passive) systems and non-GSO FSS systems, and provides values for power limits in table 1-1 of Resolution 750 (WRC-15). Mexico is also of the view that current unwanted emission limits in Resolution 750 (WRC-15) for GSO networks operating in the adjacent bands to 50.2-50.4 GHz should not be revised, since this is out of the scope of AI 1.6 and Resolution 159 (WRC-15).

DRAFT NEW RESOLUTION [A16] (WRC-19)

Protection of geostationary satellite FSS, MSS, and BSS networks from unacceptable interference from non-GSO satellite FSS systems in the 37.5-39.5 GHz, 39.5-42.5 GHz, 47.2-50.2 GHz, and 50.4-

51.4 GHz frequency bands and from non-GSO MSS systems in the 39.5-40.0 GHz and 40.0-42.5 GHz frequency bands

The World Radiocommunication Conference (2019),

considering

a) that the frequency bands 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space), and 50.4-51.4 GHz (Earth-to-space) are allocated, inter alia, on a primary basis to the fixed-satellite service (FSS) in all Regions;

b) that the frequency bands 40.5-41 GHz and 41-42.5 GHz are allocated, on a primary basis to the broadcasting-satellite service (BSS) in all regions;

c) that the frequency bands 39.5-40 GHz and 40-40.5 GHz are allocated, on a primary basis to the mobile-satellite service (MSS) in all regions;

d) that Article 22 contains regulatory and technical provisions on sharing between geostationary satellite orbit (GSO) satellite networks and non-geostationary satellite orbit (non-GSO) FSS systems in these bands in considering a); e) that, in accordance with No. 22.2, non-GSO systems shall not cause unacceptable interference to GSO FSS and broadcasting-satellite service (BSS) networks and, unless otherwise specified in the Radio Regulations, shall not claim protection from GSO FSS and BSS satellite networks; f) that non-GSO FSS systems would benefit from the certainty that would result from the quantification of technical regulatory provisions required for protection of GSO satellite networks operating in the bands referred to in considering a), b), and c) above;

g) that GSO FSS, MSS and BSS networks can be protected without placing undue constraints on non-GSO FSS systems in the bands in considering a), b), and c) above;

CCPII-2019-33-4358r1_i 30.05.19 37

h) that WRC-19 modified Article 22 to limit single-entry and aggregate permissible time allowances for degradation in terms of C/N by non-GSO FSS systems to GSO satellite networks, based on Recommendation ITU-R S.[50/40 Reference Links] and Recommendation ITU-R S.[50/40 GHz Sharing Methodology], in the bands in considering a); i) that the operating parameters and orbital characteristics on non-GSO FSS systems are usually inhomogeneous; j) that, as a result of this inhomogeneity, the time allowance for the C/N value specified in the short-term performance objective associated with the shortest percentage of time (lowest C/N) or decrease of the long-term throughput (spectral efficiency) caused to reference GSO links by non-GSO FSS systems is likely to vary between such systems;

k) that, the aggregate interference levels from multiple non-GSO FSS systems will be related to the actual number of systems sharing a frequency band based on the single-entry operational use of each system;

l) that to protect GSO FSS, MSS, and BSS networks in the frequency bands listed in considering a) from unacceptable interference, the aggregate impact of interference caused by all co-frequency non-GSO FSS systems should not exceed the maximum aggregate impact specified in No. 22.5M of the Radio Regulations; m) that the aggregate level of the time allowance for the C/N value specified in the short-term performance objective associated with the shortest percentage of time (lowest C/N) of GSO reference link is likely to be the summation of single-entry levels caused by non-GSO FSS systems,

recognizing a) that non-GSO FSS systems are likely to need to implement interference mitigation techniques, such as orbital avoidance angles, Earth station site diversity, and GSO arc avoidance, to facilitate sharing of frequencies and to protect GSO networks; b) that administrations operating or planning to operate non-GSO FSS systems will need to agree cooperatively through consultation meetings to share the aggregate interference impact allowance in a manner to achieve the level of protection for GSO FSS, MSS and BSS networks that is stated in No. 22.5M of the Radio Regulations;

c) that, taking into account the single-entry allowance in No. 22.5L, the aggregated impact of all non-GSO FSS systems can be computed without the need for specialized software tools based on the results of the single-entry impact for each system;

d) the need for administrations operating non-GSO FSS systems in the frequency bands listed in considering a) to agree cooperatively through consultation meetings takes on particular urgency whenever there could be aggregate interference at levels higher than the aggregate impact allowance from operational non-GSO FSS systems;

e) that representatives of administrations operating or planning to operate GSO FSS, MSS and BSS networks are encouraged to be involved in the determinations made pursuant to recognizing b);

CCPII-2019-33-4358r1_i 30.05.19 38

f) that in the frequency bands 37.5-39.5 GHz (space-to-Earth), 39.5-42.5 GHz (space-to-Earth), 47.2-50.2 GHz (Earth-to-space) and 50.4-51.4 GHz (Earth-to-space), signals experience high levels of attenuation due to atmospheric effects such as rain, cloud cover and gaseous absorption; g) that given these expected high levels of fading, it is desirable for GSO networks and non-GSO FSS systems to implement fade counter measures such as automatic level control, power control and adaptive coding and modulation,

noting a) that Recommendation ITU-R S.[50/40 GHz FSS Sharing Methodology] contains the methodology for determining conformity to the single-entry and aggregate limits to protect the GSO networks; b) that Recommendation ITU-R S.1503 provides recommendations on how to compute the EPFD from a non-GSO FSS system into victim earth stations and satellites; c) that Recommendation ITU-R S.[50/40 GHz FSS Reference Links] contains GSO satellite system characteristics to be considered in non-GSO/GSO frequency sharing analyses in the frequency bands 37.5-39.5 GHz, 39.5-42.5 GHz, 47.2-50.2 GHz and 50.4-51.4 GHz; resolves

1 that administrations operating or planning to operate non-GSO FSS and non-GSO MSS systems in the frequency bands referred to in considering a) above, shall, in collaboration, take all necessary steps, including, if necessary, by means of appropriate modifications to their systems or networks, to ensure that the aggregate interference into GSO FSS, MSS and BSS satellite networks caused by such systems operating co-frequency in these frequency bands does not exceed the aggregate protection limits as determined pursuant to No. 22.5M of the Radio Regulations;

2 that to carry out the obligations in resolves 1 above, administrations operating or planning to operate non-GSO FSS and non-GSO MSS systems shall agree cooperatively through regular consultation meetings referred to in recognizing b) to ensure that operations of all non-GSO networks do not exceed the aggregate level of protection for GSO satellite networks;

3 that to carry out the obligation of resolves 2, administrations shall use the GSO satellite characteristics listed in Recommendation ITU-R S.[50/40 GHz Reference Links] when applying the methodology contained in Recommendation ITU-R S.[50/40 GHz Sharing Methodology] and the results of the aggregate impact to GSO networks calculated by validation software;

4 that administrations operating or planning to operate non-GSO FSS and non-GSO MSS systems (including representatives of administrations operating GSO FSS, MSS and BSS networks) participating in a consultation meeting are allowed to use their own software in conjunction with any software tools used by the BR for the calculation and verification of the aggregate limits given in Recommendation ITU-R S.[50/40 GHz Sharing Methodology], subject to the agreement of the consultation meeting;

5 that administrations, in carrying out their obligations under resolves 1, shall take into account only those non-GSO FSS and non-GSO MSS systems with frequency assignments in the frequency bands referred to in considering a) above that have met the criteria listed in Annex 2 to this Resolution through appropriate information provided to consultation meetings referred to in resolves 2;

CCPII-2019-33-4358r1_i 30.05.19 39

6 that administrations, in developing agreements to carry out their obligations under resolves 1, shall establish mechanisms to ensure that all potential FSS and MSS system and network notifying administrations and operators are given full visibility of, and the opportunity to participate in the consultation process; [Note: Text to include initiation of process]

7 that, taking into account resolves 2, failure by a responsible administration operating or planning to operate non-GSO FSS and non-GSO MSS systems to participate in the consultation process does not relieve that administration of obligations under resolves 1 above, nor does it remove their systems from consideration in any aggregate calculations by the consultation group; 8 that each administration, in the absence of an agreement reached at consultation meetings referred to in resolves 2, shall ensure that each of its non-GSO FSS and non-GSO MSS systems subject to this Resolution are operated in accordance with reduced single-entry interference impact allowances, calculated by the apportionment of the aggregate allowance commensurate to the number of simultaneously operating non-GSO systems, so as to ensure that the aggregate allowance in No. 22.5M is not exceeded in operation;

9 that, in specific implementation of resolves 8 above, if the consultation discussions show that there would be an exceedance of the aggregate allowance from non-GSO FSS and non-GSO MSS systems in operation, every operational non-GSO FSS system shall reduce its emissions [pro rata by the amount of the exceedance of the aggregate allowance / by making appropriate modifications to their systems]:

10 that the administrations participating at the consultation meetings referred to in resolves 2 shall designate one convener to be responsible for communicating to the Bureau, such as shown in Annex 1, that the results of the aggregate non-GSO system operational calculation and sharing determinations made in application of resolves 1, 8 and 9 above, without regard to whether such determinations result in any modifications to the published characteristics of their respective systems, providing a draft record of each Consultation meeting, and providing the approved record for posting by the Bureau on the ITU website;

List of criteria for the application of resolves 5

1 Submission of Notification Publication Information.

2 Entry into satellite manufacturing or procurement agreement, and entry into satellite launch agreement.

The non-GSO FSS system operator should possess:

i) evidence of a binding agreement for the manufacture or procurement of its satellites; and

ii) evidence of a binding agreement to launch its satellites.

CCPII-2019-33-4358r1_i 30.05.19 41

The manufacturing or procurement agreement should identify the contract milestones leading to the completion of manufacture or procurement of satellites required for the service provision, and the launch agreement should identify the launch date, launch site and launch service provider. The notifying administration is responsible for authenticating the evidence of agreement.

The information required under this criterion may be submitted in the form of a written commitment by the responsible administration.

3 As an alternative to satellite manufacturing or procurement and launch agreements, clear evidence of guaranteed funding arrangements for the implementation of the project would be accepted. The notifying administration is responsible for authenticating the evidence of these arrangements and for providing such evidence to other interested administrations in furtherance of its obligations under this Resolution.

Reasons: A mechanism is required to ensure that only those administrations operating or planning to operate non-GSO FSS or MSS systems in the frequency bands under study individually or in collaboration through consultation meetings take all possible steps to ensure that the aggregate long-term interference does not exceed the performance criteria of GSO reference links.

AGENDA ITEM 1.7

CCPII-2019-33-4358r1_i 30.05.19 48

Agenda Item 1.7: to study the spectrum needs for telemetry, tracking and command (TT&C) in the space operation service for non-geostationary (NGSO) satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution 659 (WRC-15)

BACKGROUND

The demand for suitable spectrum for NGSO satellites with short duration missions is growing due to the increasing number of these types of satellite missions. The mass and dimensions of these satellites contribute to their success and their use will likely grow. These types of missions provide an affordable means for scientific and commercial space purposes and are increasingly used by new entrants in space. Nevertheless, it is important to ensure that these missions do not cause harmful interference to existing systems and incumbent services. WRC-19 Agenda Item 1.7 invites studies to accommodate spectrum requirements for telemetry, tracking and command (TT&C) in the space operation service, below 1 GHz, for NGSO satellites with short duration missions in existing bands or identify new spectrum supported by sharing studies. The term “short duration mission” used in Resolution 659 (WRC-15) refers to a mission having a limited period of validity of typically not more than 3 years, where the operator does not launch replenishment or replacement spacecraft.

The frequency ranges described under invites ITU-R 3 overlap with allocations critical to global maritime distress and safety service (GMDSS) frequencies, identified in RR Appendix 15, and centered at 156.3 MHz, 156.525 MHz, 156.65 MHz, 156.8 MHz, 161.975 MHz, and 162.025 MHz, as well as frequencies used for the safety of life COSPAS/SARSAT system in the band 406-406.1 MHz.

AGENDA ITEM 1.9, ISSUE 1.9.1



SGT2A – Radiolocation, Amateurs, Maritime & Aeronautical Coordinator: Michael Razi (CAN) Alternate Coordinator: Corali Roura (USA) Rapporteur Agenda Item: Robert Denny (USA) Alternate Rapporteur Agenda Item: Waldon Russell (BAH)

CCPII-2019-33-4358r1_i 30.05.19 51

Agenda Item 1.9.1: regulatory actions within the frequency band 156-162.05 MHz for autonomous maritime radio devices to protect the GMDSS and automatic identifications system (AIS), in accordance with Resolution 362 (WRC-15) INTRODUCTION The need to recognize and identify free-floating objects such as fishing nets, towed unpowered ships and barges, derelict ships, floating ice, wave-gliders and drifting buoys, for safety of navigation or other purposes, is resulting in a growing number of autonomous maritime radio devices (AMRDs) using automatic identification system (AIS) technology on the market, and their number continues to increase. AIS is a proven technology for global maritime safety applications, providing identification, safety of navigation, aids to navigation, and locating functions. The use of AMRDs on AIS frequencies could have an adverse impact on the safety applications of AIS by overloading the capacity of the system, and occupying maritime mobile service identities that should be reserved for ship stations and aids to navigation. As an example, some fishing net indicators may be beneficial to the safety of ship stations. However, the increasing unregulated use of these indicator devices brings some negative effects to maritime safety, mainly in the following aspects:

A large number of such devices cause a high density of visible objects in a specific vessel traffic service (VTS) area. This creates difficulties for the recognition of vessels, the assessment of navigation conditions, and the organization of vessel traffic. This increases the workload of vessel traffic services and may decrease their efficiency, compromising safety of the VTS area.

Random and autonomous transmissions of such devices are harmful to the effectiveness and efficiency of the overall AIS network. This could reduce the effectiveness of receiving messages from AIS search and rescue transponders and result in delayed emergency responses.

Given the foreseen need for future new applications or devices, the maritime community overall would benefit from harmonized technical and operational specifications for AMRDs. This agenda item addresses AMRDs operating within the frequency band 156-162.05 MHz, and whether regulatory action is required to protect global maritime distress and safety system (GMDSS) and AIS from their operations. BACKGROUND RESOLUTION 362 (WRC-15) “Autonomous maritime radio devices (AMRD) operating in the frequency band 156-162.05 MHz”, prescribes a study process for WP5B in four parts: 1) to determine the spectrum needs for the devices, 2) to categorize the various kinds of devices, 3) to conduct sharing and compatibility studies to ensure that no undue constraints are placed on the GMDSS and the AIS, and 4) to conduct studies to determine potential regulatory actions and appropriate frequencies within the band 156-162.05 MHz.

The term AMRD is not part of the Database of ITU Terms and Definitions and needs clarification for a wider audience. At the May 2017 meeting of WP 5B, it concluded on the final definition of AMRDs and provides it to IMO and IALA:

“An AMRD is a mobile station; operating at sea and transmitting independently of a ship station or a coast station. Two groups of AMRDs are identified:

CCPII-2019-33-4358r1_i 30.05.19 52

Group A: AMRDs that enhance the safety of navigation, Group B: AMRDs that do not enhance the safety of navigation (AMRDs which deliver signals or information which do not concern the vessel can distract or mislead the navigator and degrade the safety of navigation).” The devices discussed may use AIS technology; digital selective calling (DSC) technology; or transmit synthetic voice messages. Combinations of the technologies mentioned above can be found in equipment already available on the market. The ITU Bureau sent a circular letter to all administrations including a questionnaire on the distribution and applications of AMRDs. The objective of the questionnaire was to get a clear overview of these devices and to compile and categorize existing AMRDs being used in different countries. Responses were submitted to ITU-R Working Party 5B (WP 5B), the responsible group for this Agenda Item. The information was consolidated to give a general description of the applications. The applications described included uses such as diver emergency, buoy, fishnet indicators, object trackers, racing marks, and oceanographic meteorological sensors. Some AMRDs are deployed at sea, while others are carried by divers or used in the vicinity of a vessel. Although the intended use of AMRDs is at sea including coastal areas, AMRDs may be brought onto land or may be washed ashore by accident. The result shows that some devices are using AIS technology on channels AIS1 and AIS2. Other technologies, such as digital selective calling (DSC), synthetic voice, or a combination of technologies were also noted. Different transmitting power and intervals, message formats and unregulated maritime mobile service identities (MMSI) are used by many of these AMRDs. In addition to Radio Regulations (RR) Appendix 18 channels 6/16/70, AIS 1, AIS 2, and other frequency bands outside the maritime mobile service, some AMRDs operate on 121.5 MHz or 406 MHz. It can be concluded from the survey that AMRDs lack harmonized technical standards and frequency bands. The types of applications of AMRDs also vary, and AMRDs could be used in areas where they could cause interference to the land mobile service if these devices operate within the same frequency bands. DISCUSSION Group A AMRD A Group A AMRD is defined as a mobile station; operating at sea and transmitting independently of a ship station or a coast station that enhances the safety of navigation. WP 5B has concluded that Group A devices should remain subject to International Maritime Organization (IMO) International Convention for the Safety of Life at Sea (SOLAS) regulations for the communication of information to navigators on board vessels. To enhance the safety of navigation, a Group A AMRD provides information about hazard areas, such as an aid to navigation, and distress situations, such as a man overboard incident. Group A AMRDs are currently using AIS and DSC technology on the frequencies 161.975 MHz (AIS 1), 162.025 MHz (AIS 2) and 156.525 MHz (ch70). Their operation should continue to be accommodated on these frequencies in Appendix 18 of the Radio Regulations (RR) that are appropriate for aids to navigation. No additional spectrum requirement for this category of devices has been identified. The draft list of Group A AMRD applications are presented in the working document toward a draft new recommendation ITU-R M.[AMRD] in WP 5B. It currently includes applications such as: man

CCPII-2019-33-4358r1_i 30.05.19 53

overboard, drifting wreck, drifting container, iceberg, and pollution hazards. In addition, Recommendations ITU-R M.1371, M.493, and M.585 are being updated to reflect the technical characteristics of Group A AMRDs corresponding to the technology used by the devices. Group B AMRD Group B AMRDs include other maritime applications such as divers, oceanographic research, and fishing nets. Under the existing definition, Group B AMRDs do not provide information that enhances the navigation of vessels, and their usage may distract or mislead the navigator thus degrading the safety of navigation. The spectrum requirements for Group B AMRDs include one 25 kHz channel for AIS technology and up to three 25 kHz channels for other technologies. Group B AMRDs should be operated on other designated frequencies within RR Appendix 18 that are not currently used for navigational purposes. The working document toward a draft new recommendation ITU-R M.[AMRD] also contains a list of Group B AMRD applications, and technical characteristics of maximum 1 Watt output power and antenna height of 1 metre. DRAFT INTER-AMERICAN PROPOSALS It is proposed to identify frequencies 161.975 MHz (AIS 1), 162.025 MHz (AIS 2), and 156.525 MHz (ch70) in Appendix 18 of the Radio Regulations for Group A devices. It is also proposed to identify frequency 160.900 MHz (channel 2006 in Appendix 18 of Radio Regulations) for operation of Group B AMRDs using AIS technology. This frequency has been selected because it is not currently used for navigational purposes. Supports: Bahamas, Canada, Mexico, United States of America

Agenda item 1.13: to consider identification of frequency bands for the future development of International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 238 (WRC-15); BACKGROUND The aim of 5G is to create a more ‘hyper connected’ society by more comprehensively, and intelligently, integrating LTE, Wi-Fi and cellular IoT technologies, together with at least one new 5G radio interface. This will allow mobile networks to dynamically allocate resources to support the varying needs of a hugely diverse set of connections – ranging from industrial machinery in factories, to automated vehicles as well as smartphones. The significant extra capacity of the 5G radio network will need to be supported with higher bandwidth backhaul, including fibre and microwave networks. Satellite networks should also be considered for 5G backhaul while noting their limited ability to satisfy 5G’s expected latency and bandwidth requirements A central component in the evolution of all mobile technology generations has been the use of increasingly wide frequency bands to support higher speeds and larger amounts of traffic. 5G is no different, ultra-fast 5G services will require large amounts of spectrum including above 24 GHz where wide bandwidths are more readily available. Without making these higher frequency bands available for 5G, it may not be possible to deliver a step-change in mobile broadband speeds and support rapidly growing mobile data traffic, especially in busy urban areas. Spectrum above 24 GHz is well recognised worldwide as being the key component for the fastest 5G services. Without them, 5G won’t be able to deliver significantly faster data speeds or support projected extensive mobile traffic growth.

Note: This proposal has two options that need to be further discussed and finalised in the next meeting. Brazil proposed Option 1 and the United States proposed Option 2. Option 1 5.BCD113 The band 37-43.5 GHz is identified for use by administrations wishing to implement International Mobile Telecommunications (IMT) in accordance with Resolution [BCD113-40GHZ] (WRC-19). This identification does not preclude the use of these frequency bands by any application of the services to which they are allocated and does not establish priority in the Radio Regulations. Because of the potential deployment of high-density applications in the fixed-satellite service in the bands 39.5-40 GHz in Region 1, 40-40.5 GHz in all Regions and 40.5-42 GHz in Region 2 (see No. 5.516B), administrations should further take into account potential constraints to IMT in these bands, as appropriate.

DRAFT NEW RESOLUTION [BCD113-40GHZ] (WRC-19)

Terrestrial Component of IMT in the frequency band 37.5-43.5 GHz

The World Radiocommunication Conference (Sharm-El-Sheikh, 2019),

considering a) that International Mobile Telecommunications (IMT), including IMT-2000, IMT-Advanced and IMT-2020, is intended to provide telecommunication services on a worldwide scale, regardless of location and type of network or terminal; c) that the evolution of IMT is being studied within ITU-R; d) that harmonized worldwide bands for IMT are desirable in order to achieve global roaming and the benefits of economies of scale; e) that adequate and timely availability of spectrum and supporting regulatory provisions is essential to realize the objectives in Recommendation ITU-R M.2083; g) that there is a need to continually take advantage of technological developments in order to increase the efficient use of spectrum and facilitate spectrum access;

CCPII-2019-33-4358r1_i 30.05.19 64

h) that IMT systems are now being evolved to provide diverse usage scenarios and applications such as enhanced mobile broadband, massive machine-type communications and ultra-reliable and low-latency communications; i) that ultra-low latency and very high bit rate applications of IMT will require larger contiguous blocks of spectrum than those available in frequency bands that are currently identified for use by administrations wishing to implement IMT; j) that the properties of higher frequency bands, such as shorter wavelength, would better enable the use of advanced antenna systems including MIMO and beam-forming techniques in supporting enhanced broadband;

noting b) Resolution 143 (Rev. WRC-07) – “Guidelines for the implementation of high-density applications in the fixed satellite service in frequency bands identified for these applications”; c) Recommendation ITU-R M.2083 provides IMT Vision - "Framework and overall objectives of the future development of IMT for 2020 and beyond"; f) that Report ITU-R M.2320 addresses future technology trends of terrestrial IMT systems; h) Report ITU-R M.2370, on trends impacting future IMT traffic growth beyond the year 2020 and estimates global traffic demands for the period 2020 to 2030,

recognizing a) that there is a lead time between the allocation of frequency bands by world radiocommunication conferences and the deployment of systems in those bands, and that timely availability of wide and contiguous blocks of spectrum is therefore important to support the development of IMT; b) the identification of high-density applications in the fixed-satellite service in the space-to-Earth direction in the bands 39.5-40 GHz in Region 1, 40-40.5 GHz in all Regions and 40.5-42 GHz in Region 2 (see No. 5.516B); c) that Resolution 752 (WRC-07) established a power limit of -10 dBW for stations in the mobile service in the 36-37 GHz band in order to facilitate sharing between active and passive services in this band; d) that the relevant standards organizations have standardized an unwanted emission level of -13 dBm/MHz from IMT stations operating in the 37-40 GHz band, which is below the limit in recognizing c),

resolves 1 that administrations wishing to implement IMT consider the use of frequency band 37-43.5 GHz, or parts thereof, identified for IMT in RR No. 5.BCD113 and the benefits of harmonized utilization of the spectrum for the terrestrial component of IMT taking into account the latest relevant ITU-R Recommendation; Note: The invites administrations text below is supported by Brazil.

invites administrations to ensure that, when considering, nationally or regionally, the spectrum to be used for IMT, due attention is paid to the need for spectrum for other services to which the band 37-43.5 GHz is allocated, including FSS earth stations that could be deployed in a ubiquitous manner (i.e. small user earth stations) in the bands 39.5-40 GHz in Region 1, 40-40.5 GHz in all Regions and 40.5-42 GHz in Region 2, as per No. 5.516B;

invites ITU-R 1 to develop harmonized frequency arrangements to facilitate IMT deployment in the frequency bands 37-43.5 GHz taking into account the results of sharing and compatibility studies;

CCPII-2019-33-4358r1_i 30.05.19 65

2 to continue providing guidance to ensure that IMT can meet the telecommunication needs of the developing countries and rural areas in the context of the studies referred to above; 3 to update existing ITU-R Recommendations or develop new ITU-R Recommendations, as appropriate, to provide information on possible coordination and protection measures for the RAS stations in the frequency band 42.5-43.5 GHz; 4. to develop ITU-R Reports and/or Recommendations, as appropriate, to ensure coexistence between IMT and FSS, including HDFSS as per No.5.516B. 5 to develop ITU-R Recommendations, as appropriate, to provide information on possible coordination and protection measures for the existing and future SRS earth stations operating in the frequency band 37-38 GHz; 6 to develop generic unwanted emission characteristics for mobile and base stations of the terrestrial radio interfaces of IMT-2020. Reasons: The identification of the band 37-43.5 GHz to IMT will help satisfy the need for additional spectrum in the bands above 24 GHz.

Agenda Item 1.13: to consider identification of frequency bands for the future development of International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 238 (WRC-15); 45.5-47 GHz BACKGROUND Resolution 238 (WRC-15) invites ITU-R to conduct and complete in time for WRC-19 appropriate studies to determine the spectrum needs for the terrestrial component of IMT in the frequency range between 24.25 GHz and 86 GHz, as well as sharing and compatibility studies, taking into account the protection of services to which the frequency band is allocated on a primary basis, for the frequency bands:

– 24.25-27.5 GHz, 37-40.5 GHz, 42.5-43.5 GHz, 45.5-47 GHz, 47.2-50.2 GHz, 50.4-52.6 GHz, 66-76 GHz and 81-86 GHz, which have allocations to the mobile service on a primary basis; and

– 31.8-33.4 GHz, 40.5-42.5 GHz and 47-47.2 GHz, which may require additional allocations to the mobile service on a primary basis.

The Resolution further invites WRC-19 to consider, based on the results of these studies, additional spectrum allocations to the mobile service on a primary basis and identification of frequency bands for the terrestrial component of IMT. The bands to be considered are limited to part or all of the bands listed above.

The frequency band 45.5-47 MHz, or parts thereof, is allocated to the MS, the MSS, the RNS and the RNSS. The frequency bands adjacent to this frequency range are allocated to the ARS and ARSS. The details of these allocations and those of the adjacent bands are found in Article 5 of the RR.

Since no characteristics were provided for the RNS and the RNSS, the ITU-R has not conducted any sharing studies with the IMT systems.

On the other hand, there are no compatibility studies between the IMT systems in the 45.5-47 GHz band and the ARS/ARSS in the adjacent 47-47.2 GHz band. In this case, the compatibility of the IMT systems at 45.5-47 GHz with the ARS/ARSS at 47-47.2 GHz cannot be guaranteed.

– 24.25-27.5 GHz, 37-40.5 GHz, 42.5-43.5 GHz, 45.5-47 GHz, 47.2-50.2 GHz, 50.4-52.6 GHz, 66-76 GHz and 81-86 GHz, which have allocations to the mobile service on a primary basis; and

– 31.8-33.4 GHz, 40.5-42.5 GHz and 47-47.2 GHz, which may require additional allocations to the mobile service on a primary basis.

The Resolution further invites WRC-19 to consider, based on the results of these studies, additional spectrum allocations to the mobile service on a primary basis and identification of frequency bands for the terrestrial component of IMT. The bands to be considered are limited to part or all of the bands listed above.

The frequency band 47-47.2 GHz, or parts thereof, is allocated to the ARS and the ARSS. The details of these allocations and those of the adjacent bands are found in Article 5 of the RR.

In this frequency band, the ITU-R has not conducted any sharing studies between the IMT and the ARS/ARSS systems.

Considering the work done in the ITU-R and the solutions, including the points of view reflected in the CPM Report, the following proposals are made for the 45.5-47 GHz and 47-47.2 GHz frequency bands. DRAFT INTERAMERICAN PROPOSALS

CCPII-2019-33-4358r1_i 30.05.19 71

47.2-48.2 GHz BACKGROUND Mobile broadband plays an increasingly crucial role in providing access to businesses and consumers worldwide. According to International Telecommunications Union (ITU) statistics, “Mobile-broadband subscriptions have grown more than 20% annually in the last five years and are expected to reach 4.3 billion globally by end 2017” while mobile-broadband prices as a percentage of GNI per capita halved between 2013 and 2016 worldwide. Incredible technological innovation has enabled the use of higher frequency bands (e.g. mmWave) to help meet the ever-increasing demand for mobile broadband. The 47.2-50.2 GHz frequency range is shared on a co-primary basis between the Fixed, Fixed Satellite and Mobile Services in all three Regions. The Fixed Service allocation includes a global identification for high-altitude platform stations (“HAPS”) at 47.2-47.5 GHz paired with 47.9-48.2 GHz (No. 5.552A). As part of the preparations for WRC-19 agenda item 1.13, ITU-R carried out extensive sharing and compatibility studies between IMT and the Fixed Satellite Service: these studies show that sharing between the terrestrial component of IMT and the Fixed Satellite Service is feasible with a large interference margin in the 47.2-50.2 GHz frequency range. The ITU-R Working Party 5C is studying sharing and compatibility of broadband HAPS with IMT for deployment of HAPS in this band with greater rain fade mitigation. Finally, there is no need for a WRC Resolution specifying technical and operational constraints on IMT to be associated with this proposed identification for IMT. Operational characteristics that are used by cellular providers, such as base station downtilt, that change on time scales needed to minimize intra- and inter-cell interference and also guarantee quality of service should not be encoded in the Radio Regulations. Similarly, with regards to the use of the band by high density applications in the FSS (No. 5.561B), no condition is required to achieve a balance of spectrum between FSS and IMT since this is a national matter and hence should not be included in any WRC Resolution. With regards to protection of passive services in the adjacent band 50.2-50.4 GHz included in No. 5.340, no changes to Resolution 750 are necessary since No. 5.340.1 clearly states that “The allocation to the Earth exploration-satellite service (passive) and the space research service (passive) in the band 50.2-50.4 GHz should not impose undue constraints on the use of the adjacent bands by the primary allocated services in those bands.” DRAFT INTER-AMERICAN PROPOSALS

Agenda Item 1.13: to consider identification of frequency bands for the future development of International Mobile Telecommunications (IMT), including possible additional allocations to the mobile service on a primary basis, in accordance with Resolution 238 (WRC-15) BACKGROUND The frequency band 66-71 GHz is allocated on the primary basis to inter-satellite, mobile-satellite radionavigation-satellite, mobile and radionavigation services. To date, very few, studies have been carried out to confirm IMT compatibility with some of the existing or planned networks operating under these allocations as part of the preparations for World Radiocommunication Conference 2019 (WRC-19) agenda item 1.13. License-exempt access to spectrum plays a critical role in providing connectivity for users worldwide. In recognition of this fact, many countries have designated this frequency band for licence-exempt (e.g. WiGig) technologies. In the United States, the FCC decided to maintain the unlicensed use of the 64-71

GHz band1. In many administrations, the use of the 66-71 GHz band by applications in the Mobile service is regulated on a license-exempt, technology neutral basis, similar to the 2.4 GHz and 5 GHz bands. Under this approach regulators adopted rules for unlicensed devices that are designed to prevent harmful interference to authorized radio services through limits on transmitter power and spurious emissions, while industry has developed standards within the framework of these rules, generally with the intention of ensuring cooperative sharing of the spectrum by unlicensed devices. Such approach resulted in numerous benefits and innovative products for consumers. There is significant risk that identification of the 66-71 GHz band for IMT at WRC-19 would disrupt this dynamic by implying a different regulatory regime for one Mobile service application (i.e., IMT) over all others. It is also important to recognize the nascent state of license-exempt ecosystem in the 60/70 GHz frequency range. Multi-gigabit devices are just beginning to be introduced into the market. Growing demand has been driving technological developments towards much higher throughputs (20 Gbps and higher), which can be attained only with corresponding spectrum capacity. In ITU-R, significant efforts are underway to advance implementation of Multiple Gigabit Wireless Systems (MGWS) systems in 66-

71 GHz frequency band.2

It is difficult to predict how technologies, spectrum needs, market demands and other factors will evolve in this frequency range. In the absence of this understanding, an international treaty-level regulatory action on the 66-71 GHz band at WRC-19 under agenda item 1.13 would be premature and counterproductive. Identifying 66-71 GHz for IMT would do little to achieve international harmonization. Instead, such action would be highly disruptive to existing operations and discourage ongoing research and development of other types of multi-gigabit technologies.

Reasons: Studies have not been carried out in preparation for WRC-19 to show IMT compatibility with existing and planned space services networks and radionavigation systems in the 66-71 GHz band. IMT identification in the 66-71 GHz band would be counterproductive to achieving international harmonization as many administrations confirmed plans for implementation of licence-exempt technologies such as Multiple Gigabit Wireless Systems (MGWS) systems.

AGENDA ITEM 1.14 (6 440-6 520 MHz and 6 560-6 640 MHz)


(Document submitted by CITEL Member States) SGT-1 Coordinator: Luciana CAMARGOS – B – [email protected] Vice-Coordinador: José COSTA – CAN - [email protected] Agenda Item Rapporteur: Eduardo LIMA – B – [email protected] Agenda Item Vice-Rapporteur: Vassilios MIMIS – CAN – [email protected]

CCPII-2019-33-4358r1_i 30.05.19 79

Agenda Item 1.14: to consider, on the basis of ITU-R studies in accordance with Resolution 160 (WRC-15), appropriate regulatory actions for high-altitude platform stations (HAPS), within existing fixed-service allocations BACKGROUND Article 1.66A of the ITU Radio Regulations defines a high-altitude platform station (HAPS) as "a station on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth". Agenda Item 1.14 was adopted by WRC-15 to consider, in accordance with Resolution 160 (WRC-15), regulatory actions that can facilitate deployment of HAPS for broadband delivery. Resolution 160 resolves to invite ITU-R to study additional spectrum needs of HAPS, examining the suitability of existing HAPS identifications and conducting sharing and compatibility studies for additional identifications in existing fixed allocations in the 38-39.5 GHz band on a global basis and in 21.4-22 GHz and 24.25-27.5 GHz bands in Region 2 exclusively. Resolution 160 further resolves that sharing and compatibility studies are performed to ensure protection of existing services identified in the frequency ranges identified and, as appropriate, adjacent band studies, taking into account relevant studies already performed by the ITU-R. Currently there are three frequency bands identified for HAPS in the fixed services. These are:

47.2–47.5 GHz and 47.9 48.2 GHz,

27.9-28.2 GHz and 31.0-31.3 GHz,

6 440–6 520 MHz (HAPS-ground) and 6 560-6 640 MHz (ground-HAPS). However, spectrum needs of next-generation HAPS cannot be accommodated within these identifications due to either geographical restrictions or technical limitations which impair their operation. The only global identification for HAPS links (which is in the 47.2-47.5 GHz band fixed-service allocation paired with the 47.9-48.2 GHz band fixed-service allocation) suffers from the effects of rain fade attenuation that further limits service provision over high-precipitation geographies. The remaining two available bands (27.9-28.2 GHz paired with the frequency band 31.0-31.3 GHz, and 6440-6 520 MHz paired with 6 560-6 640 MHz) have been identified by a limited number of countries, none of which is within ITU Region 2. ITU-R Working Party 5C has developed Report ITU-R F.2438 assessing expected spectrum needs for broadband HAPS to be as high as 4 GHz aggregate capacity. The following table provides the terminology used in the CPM text:

BROADBAND HAPS (connectivity applications)

The technological innovations and the growing urgency to expand the availability of broadband led to a review of the current regulatory environment for delivery platforms such as HAPS. Stations operating in the stratosphere are high enough to provide service to a large area. Recent test deployments of stations delivering broadband from approximately 20 km above ground have demonstrated their maturity to provide connectivity to underserved communities with minimal ground-level infrastructure.

CCPII-2019-33-4358r1_i 30.05.19 80

Spectrum harmonization and utilization is facilitated by common worldwide identifications. International regulatory flexibility can enable improvements in global connectivity by encouraging national regulators to permit operation of higher-speed Internet access services over new, complementary platforms, while ensuring protection of existing services. Additionally, harmonization of spectrum promotes commonality of equipment, resulting in economies of scale. Advances in aeronautics and transmission technologies have significantly improved the capabilities of HAPS to provide effective connectivity solutions and meet the growing demand for high capacity broadband networks, particularly in currently underserved areas. Recently conducted full-scale test flights have shown that solar-powered platforms in the upper-atmosphere can now be used to carry payloads that offer connectivity over large areas in a reliable and cost-effective way, and a growing number of applications for the new generation of HAPS are being developed. The technology appears particularly well suited to complementing terrestrial networks by providing backhaul. A number of advantages of the new generation of HAPS are foreseen:

Wide-area coverage: A single plane will be able to serve footprints up to 100 km in diameter, and recent technological advances in the development of optical inter-HAPS links now allow the deployment of multiple linked HAPS, in fleets that can cover whole nations.

Low cost: The cost of operating solar platforms is projected to be significantly lower than other connectivity solutions in many areas, while mass production of the aircraft will significantly lower upfront capital expenditure for deployment.

Reach: HAPS platforms will operate at around 20 km above ground, which reduces their vulnerability to weather conditions that may affect service, provides large coverage areas and avoids interference caused by physical obstacles.

Rapid deployment and flexibility: It will be possible to deploy HAPS services without long lead times and it is relatively simple to return solar platforms to the ground for maintenance or payload reconfiguration.

Geographical reach: HAPS that use the architecture of solar platforms can also provide connectivity where it is unfeasible to deploy terrestrial infrastructure: remote sites on land or sea.

Environmentally friendly: HAPS can run exclusively on solar power for long periods, connecting people with almost no environmental impact.

BROADBAND HAPS (specific applications)

HAPS Broadband for specific applications is designed to focus on multiple usage cases, including: Response to natural disasters;

Fire detection, monitoring, and firefighting;

Law enforcement with communication needs across local actors and regional headquarters;

Resource exploration missions for communication between exploration teams and regional home base.

It should be noted that broadband HAPS specific applications, contrary to broadband HAPS connectivity applications, may be used for temporary periods of time in urban areas to fulfil certain of the applications mentioned above, such as emergency situations or disaster relief. It should also be noted that these specific applications will connect to only a few ground gateways during that time.

SHARING STUDIES

ITU-R WP 5C is the group responsible for Agenda Item 1.14. WP 5C has, in turn, established a specific Sharing Studies Drafting Group to examine the compatibility between HAPS and services operating or planning to operate in the bands under study as per Resolution 160 (WRC 15).

CCPII-2019-33-4358r1_i 30.05.19 81

Further resolves 1 of Resolution 160 (WRC-15) asks that ITU-R studies on AI 1.14 “include sharing and compatibility studies to ensure protection of existing services allocated in the frequency ranges identified and, as appropriate, adjacent band studies, taking into account studies already performed in ITU-R”. WP 5C has identified and carried out a number of sharing and compatibility studies, including adjacent band studies. The studies are currently provided in the Working Party 5C Chairman’s Report. The sharing and compatibility studies have been developed on a band-by-band basis as separate new reports. The studies are expected to be completed in the spring 2019 meeting of WP 5C. In general, these studies consider the impact of HAPS uplink (ground-to-HAPS) and/or downlink (HAPS-to-ground) transmissions. In most cases, the studies identify specific assumptions and methods to ensure the protection of each service. The studies are based on assumptions related to the types of deployment scenarios and technical characteristics of HAPS systems which are described in Report ITU-R F.2439 . Examples of proposed HAPS applications are given in section 1.2. In accordance with Resolution 160 (WRC-15), WP5C has developed Report ITU-R F.2439 that provides deployment and technical characteristics for the FS using HAPS stations in the frequency bands: 6 440-6 520 MHz, 6 560-6 640 MHz, 21.4-22.0 GHz, 24.25-27.5 GHz, 27.9-28.2 GHz, 31.0-31.3 GHz, 38.0-39.5 GHz, 47.2-47.5 GHz and 47.9-48.2 GHz. It provides information on broadband HAPS links for use in sharing and compatibility studies in the frequency bands listed above, as well as in adjacent bands. Furthermore WP5C developed Report ITU-R F.2438 on spectrum needs of high altitude platform stations (HAPS) broadband links operating in the fixed service.

METHODS

The Conference Preparatory Meeting of WRC-19 (CPM19-2) has completed its work on the CPM text at its February 2019 meeting and supporting studies are expected to be finalised at spring 2019 WP 5C meeting. The CPM Report contains following options/methods for each of the bands under scope of this agenda Item. There are number of different options including technical measures which may be used to address sharing and compatibility aspects with other services and applications within these bands and, as appropriate, in adjacent bands. Method A – No change The existing provisions in the Radio Regulations remain unchanged in the corresponding frequency band. Method B – Identification of bands, in accordance with Resolution 160 (WRC-15) with options

Method B1 – Revision of the regulatory provisions for HAPS in the fixed service (FS) with a primary status in bands already identified for HAPS

This may include, e.g. global or regional identification for HAPS, limitations regarding link directions, and inclusion of the technical conditions of operation of HAPS systems for the protection of other services. This could be achieved by new or revised footnotes to the Table of Frequency Allocations, and new or revised associated Resolutions.

Method B2 – Add new identification (s) for HAPS in bands already allocated to the FS with a primary status

This may include, e.g. global or regional identification for HAPS, limitations regarding link directions, and inclusion of the technical conditions of operation of HAPS systems for the protection of other services. This could be achieved by new or revised footnotes to the Table of Frequency Allocations, and new or revised associated Resolutions.

Method B3 – Add a primary allocation to the FS and a new identification for HAPS in the band 24.25-25.25 GHz (Region 2) not already allocated to the FS

This may include, primary allocation for FS in Region 2 and identification for HAPS in that Region, together with conditions e.g. limitations regarding link directions, and inclusion of the technical

HAPS Broadband spectrum requirements

HAPS spectrum for Broadband connectivity applications

HAPS systems provide fixed service connections between the platform and FS ground stations. During the development of ITU-R studies under WRC-19 Agenda item 1.14, different HAPS applications were presented. Studies within ITU based on the capacity demand for different broadband HAPS systems have developed Report ITU-R FF.2438. The overall reference capacity to be considered for determining the spectrum needs is in the order of 30 Gbps per HAPS for the forward links. Based on assumptions in these studies, results show that the current HAPS identifications will not satisfy the throughput requirements expressed for both CPE and gateway links. Those studies are based on assumptions that could be impacted by sharing analyses with incumbent services. The broadband HAPS spectrum requirements have been analysed and are provided in the following table.

HAPS Broadband spectrum requirements for specific applications

Studies within ITU, incorporated in Report ITU-R F.2438, show that 125Mbps for the forward link as well as for the return link will be sufficient to cover the broadband HAPS specific applications needs except the needs for PPDR applications (e.g. high resolution video, images, etc.) for which an additional capacity of 100 Mbps is needed for the HAPS forward and return link. This is based on the broadband PPDR capacity demand, which is addressed in Report ITU-R M.2377-0 (Annex 7). The broadband HAPS for specific applications spectrum requirements has been analysed and is provided in Table 4.

5.552A The allocation to the fixed service in the bands 47.2-47.5 GHz and 47.9-48.2 GHz is designated identified for use by high altitude platform stations (HAPS). This identification does not preclude the use of this frequency band by any application of the services to which it is allocated on a co-primary basis and does not establish priority in the Radio Regulations. The Such use of the fixed-service allocation in bands 47.2-47.5 GHz and 47.9-48.2 GHz by HAPS shall be in accordance with is subject to the provisions of Resolution 122 (Rev.WRC-0719). (WRC-0719)

Use of the bands 47.2-47.5 GHz and 47.9-48.2 GHz by high altitude platform stations in the fixed service and by other services

The World Radiocommunication Conference (Geneva Sharm el-Sheikh, 201907),

considering

a) that the band 47.2-50.2 GHz is allocated to the fixed, mobile and fixed-satellite services on a co-primary basis;

CCPII-2019-33-4358r1_i 30.05.19 110

h) that ITU-R has completed studies on compatibility between HAPS systems in the 47.2-47.5 GHz and 47.9-48.2 GHz bands and the radio astronomy service in the 48.94-49.04 GHz band;

ih) that No. 5.552 urges administrations to take all practicable steps to reserve fixed-satellite service (FSS) use of the band 47.2-49.2 GHz for feeder links for the broadcasting-satellite service (BSS) operating in the band 40.5-42.5 GHz, and that ITU-R studies indicate that HAPS in the fixed service may share with such feeder links;

ij) that the technical characteristics of expected BSS feeder links and FSS gateway-type stations are similar;

kj) that ITU-R has completed studies dealing with sharing between systems using HAPS in the fixed service and the fixed-satellite service,

recognizing

a) that, in the long term, the bands 47.2-47.5 GHz and 47.9-48.2 GHz are expected to be required for HAPS operations for both gateway and ubiquitous terminal applications, for which several administrations have already notified systems to the Radiocommunication Bureau;

b) that identification of common sub-bands for ubiquitous ground terminal applications in the use of the fixed service could facilitate HAPS deployment and sharing with other primary services in the 47.2-47.5 GHz and 47.9-48.2 GHz bands;

6.4 dB(W/MHz) for UAC (30 < 90)

22.57 dB(W/MHz) for SAC (15 < 30)

CCPII-2019-33-4358r1_i 30.05.19 111

where is the ground terminal elevation angle in degrees;

2 that the maximum transmit e.i.r.p. density levels specified in resolves 1 may be increased, using fading compensation techniques, [by up to 520 dB during periods of rain] only to compensate the rain fade, provided that the FSS short-term protection criteria is not exceeded

AGENDA ITEM 1.15


(Document submitted by CITEL Member States) SGT-1 Coordinator: Luciana CAMARGOS – B – [email protected] Vice-Coordinador: José COSTA – CAN - [email protected] Agenda Item Rapporteur: José COSTA – CAN - [email protected] Agenda Item Vice-Rapporteur: Coralí ROURA – USA - [email protected]

CCPII-2019-33-4358r1_i 30.05.19 126

Agenda item 1.15: to consider identification of frequency bands for use by administrations for the land-mobile and fixed services applications operating in the frequency range 275-450 GHz, in accordance with Resolution 767 (WRC-15) BACKGROUND Agenda Item 1.15 of the World Radiocommunication Conference 2019 (WRC-19) considers the introduction of land-mobile and fixed service applications operating in the frequency range 275-450 GHz. At present, there are no allocations to radiocommunications services above 275 GHz in the Radio Regulations (RR). However, No. 5.565 currently enables the use of the range 275-450 GHz by active and passive services on an equal basis, while inviting administrations to take all practicable steps to protect passive services.

The frequency bands included within the 275-450 GHz segment, identified for use by administrations in passive service applications, are i) 275-323 GHz, 327-371 GHz, 388-424 GHz, and 426-442 GHz for the radio astronomy service, and ii) 275-286 GHz, 296-306 GHz, 313-356 GHz, 361-365 GHz, 369-392 GHz, 397-399 GHz, 409-411 GHz, 416-434 GHz, and 439-467 GHz for the Earth exploration-satellite service (passive) and the space research service (passive). The RR allocates the 265-275 GHz frequency band to the fixed, fixed-satellite (Earth-to-space), mobile and Radioastronomy radio services for the 3 regions on a primary basis, where No. 5.149 applies.

Recent advances in microwave technology make possible the use of the frequency range 275-450 GHz by active services for communications and other uses. While optical fiber is generally the least expensive terrestrial communications medium in terms of equipment cost per Gb/s-km, there are some applications where fixed radiocommunication systems of comparable bandwidth have unique advantages. For example, in highly urbanized areas, optical fiber has very high installation costs which can greatly exceed component costs. Optical fiber cannot be installed quickly in certain place for special events and may not be economical for short-term events at a given location. Optical fiber has a time latency greater than radio systems due to the index of refraction of the fiber material which results in a group velocity about 25% less than in radio systems. While for many applications this latency is insignificant, for some applications, such as Virtual Reality (VR), Augmented Reality (AR), automation, public safety and “mission-critical” communications, it is an issue. Finally, in case of disaster, especially earthquakes with ground rupture along a fault, fiber optics systems cannot be restored quickly and temporary radio systems with comparable capacity would be beneficial in restoring communications networks for both land line service and mobile service.

In the context of the work done by the Radiocommunication Sector of the International Telecommunication Union (ITU-R) on this agenda item, Working Party 1A (WP 1A) is responsible for directing the points established in the invites of Resolution 767 (WRC-15). In view of this, WP 1A has developed Report ITU-R SM.2352 “Technological trends of active services in the frequency range 275-3.000 GHz,” which aims to provide technical information for the preparation of sharing and compatibility studies between active and passive services, and between active services.

In addition, Report ITU-R RA.2189-1 (09/2018) “Sharing between the radio astronomy service and active services in the frequency range 275-3 000 GHz” concludes that sharing between radio astronomy and active services in the range 275-3 000 GHz is possible if atmospheric characteristics as a function of height above sea level, as well as transmitter antenna directivity, are taken into account. The space research service (passive) and the Earth exploration-satellite service (passive) may also be able to share frequencies with the active services; however, studies done in PDN Report ITU-R SM.[275-450GHz SHARING] did not seek to develop regulatory provisions (such as power limits, shielding requirements and/or elevation angle restrictions, etc.) that could facilitate sharing with EESS and focused on identifying spectrum for LMS/FS applications, where such restrictions would not be necessary to protect the passive

CCPII-2019-33-4358r1_i 30.05.19 127

services. Therefore, it is possible that active service applications could share spectrum with EESS applications.

DISCUSSION

• Working Party 1A has developed a preliminary draft new Report ITU-R SM.[275-450GHZ_SHARING] “Sharing and compatibility studies between land-mobile, fixed and passive services in the frequency range 275-450 GHz” (Annex 3 to Doc. 1A/340).

• Working Parties 5A and 5C have developed draft new ITU-R Reports outlining the technical characteristics of mobile and fixed services, respectively, above 275 GHz, which have been approved in ITU-R Study Group 5: – Report ITU-R M.2417 “Technical and operational characteristics of the land mobile service

applications operating in the frequency range 275-450 GHz”: covers close proximity mobile systems operating in the frequency bands 275–325 GHz and 275–450 GHz, including description of applications and characteristics of KIOSK downloading mobile systems, ticket gate downloading mobile systems, inter-chip communication systems, intra-device communications, and wireless links for data centers; which are all high-capacity mobile applications over short distances.

– Report ITU-R F.2416 “Technical and operational characteristics and applications of the point-to-point fixed service applications operating in the frequency band 275-450 GHz” : it is noted that the 252–275 GHz frequency range is already allocated to the fixed service and if the 275–320 GHz frequency range were to also be identified for the fixed service, a continuous 68 GHz wide band could be formed.

• The CPM text for WRC-19 agenda item 1.15, is contained in Chapter 1 of the CPM Report. • The compatibility studies between EESS(passive)/RAS and LMS/FS applications concluded that the

following bands can be identified for LMS/FS applications without the need for regulatory restrictions: 275-296 GHz, 306-313 GHz, 320-330 GHz and 356-450 GHz. However, in the case where LMS/FS applications will be deployed in the same geographical area as radio-astronomy sites, separation distances and/or avoidance angles may be needed (per national arrangements) to ensure protection of radio astronomy sites from LMS/FS applications.

Reasons: The land mobile service applications described in Report ITU-R M.2417 are mainly for indoor use and shielded configurations over very short distances, which will readily permit protection of the passive services using adequate shielding. The fixed service applications are for longer term use beyond at least 5 years when new technologies and sharing techniques are expected to be available, which will be able to protect the passive services. A generic identification with conditions will offer flexibility while protecting EESS (passive) and RAS. Supports: Canada, [Guatemala], Uruguay ADD DIAP/1.15/2 5.A115 The frequency band 275-450 GHz is identified for use for fixed and land mobile service applications:

In the frequency bands 275-296 GHz, 306-313 GHz, 320-330 GHz and 356-450 GHz, no specific conditions are necessary by fixed and land mobile service applications to protect Earth exploration-satellite service (passive) applications.

In the frequency bands 275-323 GHz, 327-371 GHz, 388-424 GHz and 426-442 GHz, depending on the case, it may be necessary to adopt specific conditions (esuch as minimum separation distances and/or avoidance angles) to ensure the protection of radio astronomy stations from fixed and land mobile service applications.

In the frequency bands 296-306 GHz, 313-320 GHz, 330-356 GHz, specific conditions are necessary (such as shielding) in order to ensure the protection of Earth exploration-satellite service (passive) applications from fixed and land mobile service applications.

When considering this provision, should take into account the latest relevant ITU-R Recommendations. (WRC-19) Reasons: The ITU-R studies on the compatibility of passive and active services have shown that, depending on the specific sub-band of the 275-450 GHz frequency range and combination of active/passive service application combination, coexistence can be achieved either without needing specific conditions or with the implementation of mitigation techniques such as minimum separation distances and avoidance angles. Adequate shielding has not been ruled out as an effective mitigation technique to protect EESS. ITU-R Recommendations and Reports on coexistence between active and passive service applications are expected to evolve over time to reflect technological developments.

Support: Canada, [Guatemala], Uruguay NOC DIAP/1.15/3 5.565 Reasons: Studies have shown that sharing is feasible between applications of the LMS/FS and EESS (passive)/RAS without conditions in parts of the 275-450 GHz range. Studies also show that LMS/FS and RAS applications can coexist in other parts of the range with conditions. For the frequency ranges where EESS operates, sharing can be achieved by ensuring that transmissions from LMS/FS applications do not impact the sensitive EESS receivers through appropriate mitigation measures. Considering that the 275-450 GHz range is already available for use by all active services on a best effort basis the proposed additional footnote will provide stronger protection to passive services while keeping the balance between all active and passive service applications that can use this frequency range where there are no service allocations. Beyond the measures that can be taken at this time to achieve sharing, technology evolution and deployment conditions may further facilitate sharing. Such conditions can continue to be studied in ITU-R to provide additional guidance. Supports: Canada, [Guatemala], Uruguay SUP DIAP/1.15/4

Agenda Item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary satellite orbit;

Issue A – Bringing into use of frequency assignments to all non-GSO satellite systems, and consideration of a milestone-based approach for the deployment of non-GSO satellite systems in specific bands and services BACKGROUND:

WRC-12 and WRC-15 adopted a series of specific provisions, including RR No. 11.44B, that clarified the requirements associated with the bringing into use (BIU) and the bringing back into use (BBIU) of frequency assignments to a space station in a geostationary satellite network. However, there were no provisions adopted to address the BIU of frequency assignments to space stations in non-GSO systems. In this context, in order to complete the recording of frequency assignments to non-GSO systems, it has been the practice of the Bureau to declare the BIU of frequency assignments to non-geostationary networks and systems successfully completed when one satellite is deployed into a notified orbital plane and capable of transmitting and/or receiving those frequency assignments. This practice, reflected for FSS and MSS non-GSO systems in section 2 of the Rules of Procedure for RR No. 11.44, has been used for a number of years irrespective of the number of satellites or of the number of orbital planes indicated in the notification information provided under RR No. 11.2. During the 2015-2019 study period, the ITU-R studied both the bringing into use of frequency assignments to non-GSO systems, and the possibility of adopting a milestone-based approach for the deployment of non-GSO satellite systems comprised of multiple, multi-satellite constellations in particular frequency bands. On bringing into use (BIU), the ITU-R concluded that the practice of the Bureau noted above should be reflected in the Radio Regulations. On the milestone-based deployment approach, the ITU-R concluded that balancing the need to prevent warehousing of orbital/spectrum resources that may result from securing international recognition and protection of any non-geostationary satellite systems through the deployment of a single satellite, and the operational requirements associated with the design, development and deployment of non-GSO satellite systems, would be achieved by adoption of a milestone-based approach for the deployment of non-geostationary satellite systems. This approach would provide an additional period beyond the seven-year regulatory period in No. 11.44 for the deployment of the number of satellites, as notified and/or recorded, with the objective to help ensure that the Master International Frequency Register (MIFR) reasonably reflects actual deployment of such non-GSO systems. There is no support for applying the milestone-based approach to the science services. These proposals below reflect the general consensus developed within the ITU-R and are based on various options presented in the CPM Report for WRC-19 Agenda item 7 – issue A. Adoption of the proposals below will address both of the ITU-R conclusions, and provide a set of regulations that is equitable, and appropriately limited to addressing both the absence of a BIU standard for non-GSO systems and a milestone-based deployment approach in specific bands and services.

CCPII-2019-33-4358r1_i 30.05.19 134

As part of these proposals, the Conference is invited to instruct the ITU-R to conduct studies for the development of a technical basis for determining tolerances for various orbital parameters of non-GSO space stations. A. Proposals for Bringing into Use:

On receipt of the information n sent under this provision, the Bureau shall make that information available on the ITU website as soon as possible and shall publish it in the BR IFIC subsequently. (WRC-19)

Reasons: This new provision provides a fixed period for continuous deployment with the capability of transmitting/receiving frequency assignments to constitute BIU of frequency assignments to non-GSO systems. The start of the [thirty-day][ninety-day] period has to be before the end of regulatory period. Supports: CAN, USA

ADD DIAP/7A/5 _______________ AA 11.44C.1 For purposes of [MOD] No. 11.44C, the term “notified orbital plane” means an orbital plane of the non-GSO system, as provided to the Bureau in the most recent notification information for the system’s frequency assignments, that corresponds to Items A.4.b.4.a, A.4.b.4.d, A.4.b.4.e, and A.4.b.5.c (only for orbits whose altitudes of the apogee and perigee are different) in Table A of Annex 2 to Appendix 4. (WRC-19) Note: References to Appendix 4 items in Nos. 11.44C.1 and 11.49.4, and in Resolution [A7(A)-NGSO-MILESTONES] (WRC-19) need to be aligned with any renumbering of relevant items in Appendix 4, Annex 2, Table A that is achieved under Agenda item 7, Issue H.

Reasons: This new provision provides a description of what is meant by the term “notified orbital plane” for purposes of the new regulation in [MOD] No. 11.44C. The goal here is to characterize the orbit in a

CCPII-2019-33-4358r1_i 30.05.19 136

manner consistent with Appendix 4, but not to specify any specific orbital tolerances for individual parameters. The subject of tolerances for non-GSO system frequency assignments requires further ITU-R study in terms of the list of characteristics that may be appropriate for specification; the values of any tolerances for listed characteristics; and whether any distinction needs to be drawn for tolerances between satellite services in which non-GSO systems are operated.

(WRC-19)

Reasons: This provision creates an exception to the general rule requiring deployment into a notified orbital plane for frequency assignments to non-GSO systems that do not specify the Earth as the reference body in Appendix 4. Here, due to the variety of potential systems, mostly of a scientific nature, there is no fixed period required for confirmation of BIU by the notifying administration. Supports: CAN, USA

possible. On receipt of the information sent under this provision, the Bureau shall make that information available as soon as possible on the ITU website and shall publish it in the BR IFIC. The date on which the recorded assignment is brought back into use28, ADDDD, ADDEE, ADDFF shall be not later than three years from the date on which the use of the frequency assignment was suspended, provided that the notifying administration informs the Bureau of the suspension within six months from the date on which the use was suspended. If the notifying administration informs the Bureau of the suspension more than six months after the date on which the use of the frequency assignment was suspended, this three-year time period shall be reduced. In this case, the amount by which the three-year period shall be reduced shall be equal to the amount of time that has elapsed between the end of the six-month period and the date that the Bureau is informed of the suspension. If the notifying administration informs the Bureau of the suspension more than 21 months after the date on which the use of the frequency assignment was suspended, the frequency assignment shall be cancelled. (WRC-195)

Reasons: The addition of new footnotes ADDDD, ADDEE and ADDFF is necessary to allow the establishment of parallel provisions for bringing frequency assignments to non-GSO systems back into use following a suspension. The other changes are for editorial improvement.

RESOLUTION [A7(A)-NGSO-MILESTONES] (WRC-19)

A milestone-based approach for the implementation of frequency assignments to space stations in a non-geostationary-orbit satellite system

in certain bands and services


considering

a) that filings for frequency assignments to non-geostationary orbit (non-GSO) satellite systems comprised of hundreds to thousands of non-GSO satellites have been received by the ITU since 2011, in particular in frequency bands allocated to the fixed-satellite service (FSS) or the mobile-satellite service (MSS);

b) that design considerations, availability of launch vehicles to support multiple-satellite launches, and other factors mean that notifying administrations may require longer than the regulatory period stipulated in [MOD] No. 11.44 to complete implementation of non-GSO systems referred to in considering a);

c) that any discrepancies between the deployed number of orbital planes/satellites per orbital plane of a non-GSO system and the Master International Frequency Register (Master Register) have, to date, not significantly impinged upon the efficient use of the orbital/spectrum resource in any frequency band used by non-GSO systems;

d) that the bringing into use and the recording in the Master Register of frequency assignments to space stations in non-GSO systems by the end of the period referred to in [MOD] No. 11.44 do not require the confirmation by the notifying administration of the deployment of all the satellites associated with these frequency assignments;

e) that ITU-R studies of the issue have shown that the adoption of a milestone-based approach will provide a regulatory mechanism to help ensure that the Master Register reasonably reflects the actual deployment of such non-GSO satellite systems in certain frequency bands and services, and improve the efficient use of the orbital/spectrum resource in those frequency bands and services;

CCPII-2019-33-4358r1_i 30.05.19 141

f) that in defining the timeline and objective criteria for the milestone-based approach, there is a need to seek a balance between the prevention of spectrum warehousing, the proper functioning of coordination mechanisms and the operational requirements related to the deployment of a non-geostationary satellite system;

g) that extensions to milestones are undesirable, as they create uncertainty with respect to the non-GSO FSS system with which other systems must coordinate,

recognizing

a) that [MOD] No. 11.44C addresses the bringing into use of frequency assignments to non-GSO satellite systems;

b) that any new regulatory mechanism for management of frequency assignments to non-GSO systems in the Master Register should not impose an unnecessary burden;

c) that the number of orbital planes in a non-GSO system (item A.4.b.1) and the number of satellites in each orbital plane (item A.4.b.4.b) are among the notified required characteristics as specified in Appendix 4;

d) that since [MOD] No. 13.6 is applicable to non-GSO systems with frequency assignments that were confirmed to have been brought into use prior to 1 January 2021 in the frequency bands and services to which this Resolution applies, transitional measures are required to provide affected notifying administrations the opportunity to either confirm deployment of satellites in accordance with the notified required characteristics as specified in Appendix 4, or to complete deployment in accordance with this Resolution;

e) that for frequency assignments to non-GSO system brought into use and having reached the end of the period referred to in [MOD] No. 11.44 prior to 1 January 2021 in the frequency bands and services to which this Resolution applies, affected notifying administrations should be given the opportunity to either confirm the completion of the deployment of satellites in accordance with the Appendix 4 characteristics of their recorded frequency assignments, or be given sufficient time to complete deployment in accordance with this Resolution; f) that it is not necessary or appropriate for the Bureau, in the interest of improving the efficient use of the orbital/spectrum resource or otherwise, to routinely use the procedures of [MOD] No. 13.6 to seek confirmation of the deployment of the number of satellites in notified orbital planes for non-geostationary satellite orbit systems in frequency bands and services not listed in resolves 1 of this Resolution;

g) that [MOD] No. 11.49 addresses the suspension of recorded frequency assignments to a space station of a satellite network or to space stations of a non-geostationary satellite system,

recognizing further

that this Resolution relates to those aspects of non-GSO systems to which resolves 1 applies with regard to the notified required characteristics as specified in Appendix 4. The conformity of the notified required characteristics of the non-GSO systems other than those referred to in recognizing d) above is outside the scope of this Resolution,

noting

that for the purpose of this Resolution:

− the term “frequency assignments” is understood to refer to frequency assignments to a space station of a non-geostationary-satellite orbit system;

− the term “notified orbital plane” means an orbital plane of the non-GSO system, as provided to the Bureau in the most recent notification information for the system’s

CCPII-2019-33-4358r1_i 30.05.19 142

frequency assignments, that corresponds to Items A.4.b.4.a, A.4.b.4.d, A.4.b.4.e, and Item A.4.b.5.c (only for orbits whose altitudes of the apogee and perigee are different) in Table A of Annex 2 to Appendix 4;

− the term “total number of satellites” is understood to mean the sum of the various values of Appendix 4 data item A.4.b.4.b associated with the notified orbital planes,

resolves

1 that this Resolution applies to frequency assignments to non-geostationary satellite systems brought into use in accordance with [MOD] Nos. 11.44 and/or [MOD] 11.44C, in the frequency bands and for services listed in the Table below:

AGENDA ITEM 7, ISSUE B



154 CCPII-2019-33-4358r1_i 30.05.19

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Issue B - Application of coordination arc in the Ka-band, to determine coordination requirements between the FSS and other satellite services BACKGROUND: During the study period leading to the 2019 World Radiocommunication Conference, the ITU performed various studies on the convergence between the Mobile-satellite (MSS) and the fixed-satellite (FSS) services in portions of the Ka-bands. In particular, the characteristics of the GSO MSS earth stations and those of the GSO FSS earth stations filed for the 29.5-30 GHz/19.7-20.2 GHz bands were compared especially in terms of antenna size and antenna patterns. Not only did these studies concluded that GSO MSS and GSO FSS earth stations are similar but they also revealed that most of the filing contained frequency assignments for both MSS and FSS in the same frequency ranges in the 29.5-30 GHz/19.7-20.2 GHz bands. In view of these results and in particular the similarities between FSS and MSS frequency assignments to a GSO space station in the 29.5-30 GHz/19.7-20.2 GHz bands, it is justified to define a single coordination trigger for the identification of coordination requirements involving GSO FSS assignments, GSO MSS assignments or GSO FSS and GSO MSS assignments in the 29.5-30/19.7-20.2 GHz.

Under the current regulatory framework, the requirements for coordination of GSO FSS assignments in the band referred to above results from an orbital separation of less than ±8 degrees between the GSO space stations of the respective systems while the coordination requirements for GSO MSS assignments or for GSO MSS versus GSO FSS assignments or vice versa are identified based on the calculation of the anticipated increase of the noise temperature of a system due to the interference from the other system. It is proposed to modify Appendix 5 of the Radio Regulations to extend the use of the coordination arc approach (orbital separation of ±8 degrees) for the identification of all the coordination requirements under No. 9.7 (GSO vs GSO) in the 29.5-30 GHz/19.7-20.2 GHz bands. The introduction of an 8 degree coordination arc would serve as a substitution of the existing coordination trigger of ΔT/T > 6%. It would also reduce the number of Administrations identified for coordination, thereby reducing the number of coordination processes and resulting in a reduction of required resources in Administrations, operators, and Bureau. Administrations will continue to have the possibility to request application of RR No. 9.41 for inclusion of additional affected satellite networks, taking into account the ΔT/T > 6% criteria.

These proposed modifications to Appendix 5 to the Radio Regulations are based on the single method of the CPM report on WRC-19 agenda item 7, Issue B. DRAFT INTER-AMERICAN PROPOSAL:

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Issue C - Issues for which consensus was achieved in ITU-R Issue C is a collection of several different topics that are viewed as being straightforward and for which consensus was readily achieved within ITU-R. The issues address such things as resolving inconsistencies in regulatory provisions, clarifying certain existing practices, or increasing transparency in the regulatory process. BACKGROUND: It is generally recognized that provisions in Appendix 30B relating to coordination and notification were actually written on the model of provisions in Article 9 and 11. In particular, we note that paragraph §8.13 of Article 8 in Appendix 30B is similar to No. 11.43A except for the use of the word “notified” instead of “recorded” although both provisions deal with modifications to frequency assignments in the MIFR. The differences between the two terms were deemed significant enough to create an issue under agenda item 7. In response to this issue, the ITU-R developed [Preliminary draft] CPM Report with a single Method for the alignment of §8.13 of Article 8 in Appendix 30B with No. 11.43A. It is proposed to implement the modifications to the Radio Regulations in accordance with this Method. DRAFT INTER-AMERICAN PROPOSAL: Supports: B, MEX, CAN MOD DIAP/7(C1)/1

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Issue C - Issues for which consensus was achieved in ITU-R Issue C is a collection of several different topics that are viewed as being straightforward and for which consensus was readily achieved within ITU-R. The issues address such things as resolving inconsistencies in regulatory provisions, clarifying certain existing practices, or increasing transparency in the regulatory process. BACKGROUND: RR Appendix 30B consists of two blocks/sub-bands of 250 MHz each in 10-11 GHz frequency range, i.e. 10.70-10.95 GHz, 11.2-11.45 GHz for the downlink and 12.75-13.0 GHz, 13.0-13.25 GHz for the uplink. Submission from administrations when applying Article 6 of RR Appendix 30B for additional use usually covers both blocks/sub-bands of 250 MHz as mentioned above or may only submit either of the two blocks for additional use, or while successfully applying Article 6 for the two blocks/sub bands, when applying Article 8 only bring into use one block/sub-band of 11/13 GHz. There is no provision in RR Appendix 30B prohibiting, strictly speaking, an Administration from submitting an application for one of the blocks/sub-bands in an explicit submission. However, there is no specific provision authorizing that application when submitting RR Appendix 4 for either of the blocks/sub-bands. In response to this problem, ITU-R developed a [draft] report of the CPM with a unique approach to this issue, which is to add a footnote to Paragraph 6.1 of Article 6 of RR Appendix 30B, to allow:

a) Submit, in accordance with Paragraph 6.1, an additional use for the two blocks/sub-bands in 10-11 GHz, but only put into service one of the blocks/sub-bands, or

b) Submit, in accordance with Paragraph 6.1, an additional use for only one of the two blocks/sub-

bands in 10-11 GHz, and notify and put into service that block/sub-band;

c) Enable the Bureau, by applying Article 6, to process the application according to its submission, that is, to process the two blocks/sub-bands or process one of the two blocks/sub-bands and continue processing the application as received;

d) Enable the Bureau, by applying Article 8, to process only one of the two blocks/sub-bands, although the two blocks/sub-bands have been requested by an administration under Article 6 or has been successfully coordinated under Article 6 but only one block/sub-band has been put into use.

It is proposed to apply the additions to the Radio Regulations according to the single method proposed by the ITU-R.

Agenda item 7 to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary satellite orbit; Resolution 86 (Rev.WRC-07) – Implementation of Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference Issue C - Issues for which consensus was achieved in ITU-R and a single method has been identified Issue C is a collection of several different topics that are viewed as being straightforward and for which consensus was readily achieved within ITU-R. The issues address such things as resolving inconsistencies in regulatory provisions, clarifying certain existing practices, or increasing transparency in the regulatory process. Issue C3 addresses the consequences for not replying to the letters from the Bureau initiated by a request for its assistance by a notifying administration seeking the inclusion of the territory of a foreign administration under §6.6 of RR Appendix 30B. Background: An administration intending to convert an RR Appendix 30B allotment into an assignment, introduce an

additional system3 or modify the characteristics of an assignment in the Appendix 30B List must submit the information specified in Appendix 4 to the Bureau. Following the receipt of the notice, the Bureau examines and publishes it in a special section of the BR IFIC. Among other things, this special section can contain two types of requirements to seek and obtain the agreement of those affected administrations whose:

– allotments in the Appendix 30B or assignments in the Appendix 30B List or those already examined by the Bureau (requirements identified under § 6.5 of Appendix 30B), or

– territories have been included in the service area of the assignment under consideration (requirements associated with §6.6 of Appendix 30B).

It is important to note that under the current regulatory framework, there is a specific provision (§ 6.13) in Appendix 30B to seek the assistance of the Bureau in case of a non-response of an affected administrations identified under § 6.5 of Appendix 30B within the four-month comment period. In case of a non-response to the letters from the Bureau initiated under § 6.13, 6.14 and 6.14bis of Appendix 30B, it will be deemed that this administration, identified under § 6.5 of Appendix 30B has agreed as per § 6.15 of Appendix 30B. However, none of the provisions referred above (§ 6.13 to 6.15) applies in the case of affected administrations identified under § 6.6 of Appendix 30B. In fact, there is not a single regulatory mechanism in Appendix 30B to seek the assistance of the Bureau in this case. For a request for the assistance of the Bureau on issue relating to the inclusion of the territory of an administration, the notifying administration, in its request to the Bureau and the Bureau, in its subsequent letters to the 3 See § 2.6 of RR Appendix 30B.

CCPII-2019-33-4358r1_i 30.05.19 169

affected administration, have to invoke RR No. 13.1 for this matter. Furthermore, the current Radio Regulations do not specify any action from the Bureau with respect to an administration that did not respond to any of its letters initiated under RR No. 13.1. This implies that the inclusion of the territory of an administration identified under § 6.6 of RR Appendix 30B can only result from a formal agreement of this administration and, in no circumstance, results from a non-response to neither the original request for inclusion of its territory nor any subsequent letters from the Bureau on this matter. (Source Document: 4624/18 ) One single method has been identified to address this problem. The method consists of adding a new provision into Article 6 of RR Appendix 30B to clearly establish that § 6.13 to § 6.15 of RR Appendix 30B do not apply in the context of the requirements associated with § 6.6 of RR Appendix 30B.

BACKGROUND:

Normally, at the end of the coordination process under Article 4 of RR Appendices 30 and 30A and when a network is about to be implemented, two separate but identical notices are submitted for entry into the List under § 4.1.12 for Regions 1 and 3 or for the modifications to the Plans under § 4.2.16 for Region 2 and for Notification under §§ 5.1.1 and 5.1.2 of RR Appendices 30 and 30A, respectively, at the same time. Therefore, it would reduce the workload of both administrations and the Bureau if one notice could be submitted, treated as, and examined in respect of the relevant provisions of Articles 4 and 5 of RR Appendices 30 and30A, respectively. Looking at the RR Appendix 4 information required for notices under § 4.1.12 or § 4.2.16 and § 5.1.1/5.1.2, these would seem to be identical for entry into the List for Regions 1 and 3 or modification of the Plans for Region 2 and Notification. Therefore, the data requirements of RR Appendix 4 should not create any practical difficulties in having a single notice submitted to complete both processes under the relevant provisions of Articles 4 and 5 of RR Appendices 30 and 30A. In this contribution, it is proposed to implement the modifications to the Radio Regulations in accordance with single method to address this issue. DFAFT INTER-AMERICAN PROPOSALS:

The issues address such things as resolving inconsistencies in regulatory provisions, clarifying certain existing practices, or increasing transparency in the regulatory process. BACKGROUND: If an administration completes the procedures through the Bureau, both the registration in the list of Appendix 30B as per RR 6.17 and the notification under RR 8.1, it must meet the requirements provided in Appendix 4 of the RR according to the type of request submitted. The same information requirements could be established, but depending on the request, more technical specifications are required, so the information in 6.17 could become the information in 8.1. It is proposed that additions to the Radio Regulations be applied in accordance with the single method proposed by the ITU-R in order to simplify the process and reduce the workload of the Radiocommunication Bureau and the Administrations. METHOD The ITU-R identified a single method to fulfill this item. This method proposes amending paragraph 6.17 of Article 6 of Appendix 30B of the RR and Appendix 4 of the RR to make it possible to deal with both provisions on the basis of one single submittal.

Agenda Item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary satellite orbit; Resolution 86 (Rev.WRC-07) – Implementation of Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference Issue C - Issues for which consensus was achieved in ITU-R Issue C is a collection of several different topics that are viewed as being straightforward and for which consensus was readily achieved within ITU-R. The issues address such things as resolving inconsistencies in regulatory provisions, clarifying certain existing practices, or increasing transparency in the regulatory process. Issue C7: Taking into account that the possibility of obtaining agreement from affected administrations for a specified period would considerably facilitate the tasks of those administrations applying Article 4 of RR Appendices 30 and 30A as well as Article 6 of RR Appendix 30B, it is proposed to amend RR Appendices 30A and 30B to be harmonized among RR Appendices 30, 30A and 30B. BACKGROUND Taking into account that the possibility of obtaining agreement from affected administrations for a specified period would considerably facilitate the tasks of those administrations applying Article 4 of RR Appendices 30 and 30A, it is proposed to amend RR Appendices 30A and 30B to be harmonized among RR Appendices 30, 30A and 30B. METHOD TO SATISFY ISSUE C7 A single method has been identified to address this issue. This method would add a new provision 6.15bis to Article 6 and a new provision § 8.16bis to Article 8 of RR Appendix 30B in order to recognize the possibility of obtaining agreement from affected administrations for a specified period. In addition, in order to make harmonization of RR Appendix 30B and RR Appendices 30 and 30A, modification to § 5.2.6 to Article 5 of RR Appendix 30A would be necessary.

186 CCPII-2019-33-4358r1_i 30.05.19

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Issue D – Identification of those specific satellite networks and systems with which coordination needs to be effected under RR Nos. 9.12, 9.12A and 9.13

BACKGROUND: The 2012 World Radiocommunication Conference (WRC-12) decided to modify RR No. 9.36.2 to Article 9 of the Radio Regulations. Since then, the Bureau publishes a “definitive list” of those networks, systems and earth stations with which coordination under RR Nos. 9.7, 9.7A and 9.7B needs to be effected upon receipt of coordination request for a satellite network or system. Such a list is published in the relevant Special Section of the BR International Frequency Information Circular (BR IFIC). However, in the cases of coordination under RR Nos. 9.12, 9.12A and 9.13, the Bureau does not publish a list of the potentially affected satellite networks or systems to complement the list of administrations potentially affected by incoming satellite networks or systems that they do provide. In response to this issue, the ITU-R developed a CPM report with two methods: Method D1 for the publication of a definitive list of satellite networks and systems and method D2 for the publication of a list of potentially affected satellite networks or systems for information only. In this contribution, it is proposed to implement the modifications to the Radio Regulations in accordance with Method D1. DRAFT INTER-AMERICAN PROPOSALS:

AGENDA ITEM 7, ISSUE E



189 CCPII-2019-33-4358r1_i 30.05.19

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Issue E - Resolution related to RR Appendix 30B

BACKGROUND: The administrations that wish to convert their national allotment included in Appendix 30B of the RR into an assignment with characteristics that exceed the initial allotment or wish to introduce a new network will have to tackle difficulties such as: a) submitting a request for conversion to the Bureau, which would be included on the waiting list after the last submission received; and b) when its turn for processing arrives, because of the nature of the additional systems/uses concerned, it is extremely difficult—if not completely impossible—to conduct a successful coordination within the time-limits set by the regulations. In short, there are few probabilities that an administration can successfully complete the coordination for the conversion of its national allotment to assignments with characteristics that go beyond the initial allotment within the time-limits set by the regulations. In that respect, ITU-R deems that the above can be addressed in a WRC Resolution as a measure and special procedure applied once only, to facilitate processing its submission in accordance with Appendix 30B of the RR and to enhance equitable access of developing countries to spectrum / orbital resources. METHOD: ITU-R proposes the establishment of special measures that would be applicable once only with respect to communications filed by administrations that lack frequency assignments on the List of Appendix 30B of the RR and which would be specified in a WRC Resolution for the purpose of facilitating the work carried out by said administrations to facilitate viable satellite services on terms that are economical for their national territories. In that respect, ITU-R identified, as the only method, the drafting of a WRC Resolution based on Resolution 553 (Rev. WRC-15) that addresses a similar problem in the frequency band 21.4-4.22 GHz in the broadcasting-satellite service for Regions 1 and 3. It also proposes a modification to the footnote of Article 6 of Appendix 30 B of the RR.

CITEL Administrations agree with the method proposed by the ITU-R because the Resolution that is being proposed would be applicable to Regions 1, 2, and 3. In addition, the proposed method would address the issue that the procedure would only be used once by an administration and would be confined to the national service and coverage area; the request would be examined with a priority date; and relaxed coordination would apply to certain network categories, aimed at avoiding unnecessary coordination. In addition, a reduced coordination arc with the same values as those adopted by WRC-15 for the non-planned bands is included as part of the proposed solution to further alleviate the coordination burden for submissions made under the Resolution.

DRAFT NEW RESOLUTION [A7(E)-AP30B] (WRC-19)

Additional measures for satellite networks in the fixed-satellite service in frequency bands subject to Appendix 30B for the enhancement

of equitable access to these frequency bands


Considering

a) that WARC Orb-88 created an allotment Plan for the use of the frequency bands 4 500-4 800 MHz, 6 725-7 025 MHz, 10.70-10.95 GHz, 11.20-11.45 GHz and 12.75-13.25 GHz;

b) that WRC-07 revised the regulatory regime governing the use of the frequency bands mentioned in considering a) above,

considering further

a) the additional regulatory measures for the enhancement of equitable access included in Resolution 553 (WRC-15);

b) that the Rule of Procedure on No. 9.6 of the Radio Regulations states that “the intent of Nos. 9.6 (9.7 to 9.21), 9.27 and Appendix 5 is to identify to which administrations a request for coordination is to be addressed, and not to state an order of priorities for rights to a particular orbital position”,

recognizing

a) that Article 44 of the ITU Constitution lays down the basic principles for the use of the radio-frequency spectrum and the geostationary-satellite and other satellite orbits, taking into account the needs of developing countries; 2bis Draft new Resolution [A7(E)-AP30B] (WRC-19) applies.

191 CCPII-2019-33-4358r1_i 30.05.19

b) that the “first-come first-served” concept can restrict and sometimes prevent access to and use of certain frequency bands and orbit positions;

c) the relative disadvantage for developing countries in coordination negotiations due to various reasons such as a lack of resources and expertise;

d) that Resolution 2 (Rev.WRC-03) resolves that “the registration with the Radiocommunication Bureau of frequency assignments for space radiocommunication services and their use do not provide any permanent priority for any individual country or groups of countries and do not create an obstacle to the establishment of space systems by other countries”,

recognizing further

a) that information provided by the Bureau into ITU-R studies indicate that significant numbers of Appendix 30B submissions have been received by the Bureau in the time period 1 January 2013 until 30 June 2018 and that the table below summarizes the data provided by the Bureau into those studies and shows the variations for the number of networks at the various stages;

*** The above table needs to be replaced by that provided by the Bureau before the start of WRC-19

b) that the number of Appendix 30B submissions made by some administrations is large, which may not be realistic;

c) that the use of certain combinations of technical parameters in submissions (e.g. high-gain receiving space station antennas) can make the systems/submissions overly sensitive to interference in such a way that

193 CCPII-2019-33-4358r1_i 30.05.19

subsequent submissions for conversion from allotment into assignments with change would cause interference to those systems,

taking into account

that the majority of Appendix 30B submissions under § 6.1 have global coverage and service area, which is typically changed limited service area with considerably wider coverage area at the time of § 6.17 submission, notwithstanding the Note to Appendix 4 data item B.3.b.1 which states “Taking due account of applicable technical restrictions and allowing some reasonable degree of flexibility for satellite operations, administrations should, to the extent practicable, align the areas the satellite steerable beams could cover with the service area of their networks with due regard to their service objectives” and this is complicating coordination for administrations attempting to convert their national allotments into assignments or introducing an additional system for national use in a technically and economically viable manner,

resolves

that as of the date (yet to be decided by WRC-19), the special procedure described in the Attachment to this Resolution for processing of submissions received by the Bureau under Article 6 of Appendix 30B for conversion of the allotment of an administration into an assignment with modifications which are outside the envelope of the initial allotment while restricted to provide service to its national territory designated by test points as contained in the corresponding allotment, or submission by an administration of an additional system the service area of which is limited to its national territory designated by test points as contained in the allotment, in the frequency bands 4 500-4 800 MHz, 6 725-7 025 MHz, 10.70-10.95 GHz, 11.20-11.45 GHz and 12.75-13.25 GHz shall be applied if requested by an administration in respect of its submission as specified in the Attachment below.

ATTACHMENT TO DRAFT NEW RESOLUTION [A7(E)-AP30B] (WRC-19)

Additional measures for satellite networks in the fixed-satellite service in frequency bands subject to Appendix 30B for the enhancement

8 The provisions in this Attachment are supplementary to the provisions of Article 6 of Appendix 30B.

APPENDIX 1 TO ATTACHMENT TO DRAFT NEW RESOLUTION [A7(E)-AP30B] (WRC-19)

Criteria for determining whether an assignment is considered to be affected by networks submitted to Appendix 30B under this Resolution

The criteria as contained in Annex 4 of Appendix 30B continue to apply in order to determine if a proposed new assignment applying the procedures of this Attachment affects:

a) national allotments in the Plan;

b) an assignment stemming from the conversion of an allotment into an assignment without modification or with modification inside the envelope of the allotment;

c) allotment requested under Article 7 of Appendix 30B by a new Member State of the Union which has received unfavourable findings under Article 7 and has been subsequently treated as a submission under § 6.1 of Appendix 30B;

d) assignments stemming from the application of § 6.35 of Appendix 30B;

e) assignments for which the procedures of this Resolution have been previously applied.

An assignment which appears in the List or which the Bureau has previously examined after receiving complete information and published under § 6.7 of Appendix 30B, which does not fall into any of the above 1 The Bureau shall also identify the specific satellite networks with which coordination needs to be effected. 2 If the payments are not received in accordance with the provisions of Council Decision 482, as amended, on the implementation of cost recovery for satellite network filings, the Bureau shall cancel the publication, after informing the administration concerned. The Bureau shall inform all administrations of such action and that the network specified in the publication in question no longer has to be taken into consideration by the Bureau and other administrations. The Bureau shall send a reminder to the notifying administration not later than two months prior to the deadline for the payment in accordance with the above-mentioned Council Decision 482 unless the payment has already been received.

AGENDA ITEM 7, ISSUE G



199 CCPII-2019-33-4358r1_i 30.05.19

Agenda Item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit Issue G: Updating the reference situation for Regions 1 and 3 networks under RR Appendices 30 and 30A when provisionally recorded assignments are converted into definitive recorded assignments BACKGROUND § 4.1.18 of Appendices 30 and 30A of the Radio Regulations prescribes that in the case of recording in the List with outstanding coordination requirements, this recording shall be provisional, but that the entry shall be changed from provisional to definitive recording in the List if the Bureau is informed that the new assignment in the Regions 1 and 3 List has been in use, together with the assignment which was the basis for the disagreement, for at least four months without any complaint of harmful interference being made. When the provisional recording becomes definitive, the reference situation of the interfered-with network will be updated. This could severely affect the reference situation of the interfered-with network. There is a similar, but different, provision applicable in Region 2, § 4.2.21A of Appendices 30 and 30A. The Region 2 provisions are applicable to a much smaller subset of services with no potential impact to the reference situation of the interfered-with network. In preparations for WRC-15 it was too late to have this issue raised and captured in the Conference Preparatory Meeting (CPM) Report. Subsequently, this issue was brought to the attention of the RRB-70 meeting in October 2015 (Document RRB-70/10), requesting that a Rule of Procedure (RoP) be prepared to outline the desired practice to be followed by the Bureau. RRB-70 however was of the view that such a RoP would consist in a change of the Radio Regulations and therefore was outside the authority of the RRB. Following this decision, a late contribution on this issue was submitted to WRC-15 which has the authority to make changes to the Radio Regulations, Document WRC-15/169. Since this proposal was made directly to the Conference with no previous studies, WRC-15 decided that “….it was felt that further study of this issue is required if this current practice is to be changed. ITU-R is therefore invited to study this issue under the standing agenda item 7 with the aim of finding an appropriate regulatory and technical solution to this issue.” Issue G is in response to these activities before and during the last Conference and the decision of WRC-15.

Agenda Item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07), in order to facilitate rational, efficient and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Resolution 86 (Rev.WRC-07) – Implementation of Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference

Agenda item 7(H) Issue H – Modifications to RR Appendix 4 data items to be provided for non-geostationary satellite systems with multiple orbital planes BACKGROUND: Issue H consolidates three different issues that were developed during the ITU-R preparatory process for WRC-19 agenda item 7. Issue H relates to the need to ensure that enough RR Appendix 4 data items are provided to facilitate modelling non-geostationary (non-GSO) satellite systems in order for:

- potentially affected administrations to be able to identify the potential impacts of these systems on their own systems and to formulate their comments to the notifying administration and the Radiocommunication Bureau based on the advance publication information (API) in the case of frequency assignments to non-geostationary satellite systems not subject to coordination under Section II of RR Article 9 (see No. 9.3) or the Coordination Request (CR/C) in the case of frequency assignments to non-GSO satellite systems subject to Section II of RR Article 9 (see No. 9.52), or,

- the Radiocommunication Bureau to be able to perform an examination with respect to compliance

with the RR Article 22 epfd limits based on the latest version of the algorithm contained in Recommendation ITU-R S.1503; and

- administrations and the Radiocommunication Bureau to understand whether the frequency assignments to a non-GSO satellite system define a single non-GSO system or multiple mutually exclusive configurations and, in the case of the latter, the nature of the mutually exclusive configurations.

As a result, ITU-R identified a single method to address this Issue. This method proposes:

- to extend the requirement to provide items for frequency assignments of non-GSO systems in frequency bands subject to coordination under Section II of RR Article 9 of RR Appendix 4 parameters (namely the right ascension of the ascending node, the longitude of the ascending node and the associated date and time, the argument of the perigee) to API and notification filings for frequency assignments to non-GSO systems in frequency bands not subject to coordination under Section II of RR Article 9. Those requirements would apply only for non-GSO systems, for which the relative distribution of the orbital planes and satellites is known, identified by additional RR Appendix 4 data items. It is also proposed to add new RR Appendix 4 data items for frequency assignments to non-GSO systems in frequency bands not subject to coordination under Section II of RR Article 9: mandatory items, identifying whether the orbit is sun-synchronous or not, and optional items, providing the local time of the ascending node (LTAN) for sun-synchronous orbits;

- to add new RR Appendix 4 data items: an indicator of whether all of the orbital planes define a single non-GSO system or multiple mutually exclusive configurations and in the case of the latter, another RR Appendix 4 data item for the number of mutually exclusive configurations and another

204 CCPII-2019-33-4358r1_i 30.05.19

RR Appendix 4 data item for the provision of an exhaustive list of the potential orbital plane configurations;

- changes to RR Appendix 4 data items as a consequence of the revision of Recommendation ITU-R S.1503 to improve the ability to define sub constellations with different sets of parameters per sub constellation (e.g. minimum angle to the GSO arc that varies by orbit plane), the ability to define different sets of system operating parameters by frequency band and provide additional degrees of flexibility in existing fields (e.g. possibility of having the minimum elevation angle varying by latitude and azimuth).

Considering the data to be provided of non-geostationary orbit satellite systems, the CITEL administrations support the updating of RR Appendix 4 according to the single method that satisfies Agenda Item 7, issue H, identified in the second session of the Conference Preparatory Meeting (CPM) 2019, consisting in the addition and modification of some numerals, as indicated in the only Annex of the present proposal. The following modifications to Appendix 4 Annex 2 are proposed in order to improve the description of non-GSO satellite systems as indicated in the background.

Reasons: The RR Appendix 4 Update allows Administrations to have enough information to identify potential interference scenarios, taking into account the flexibility that may be required for non-GSO satellites with short duration missions and satellites for scientific or experimental purposes. Also, with information related to several orbital planes and their relationship with respect to the non-GSO system. On the other hand, updating is also considered to align Appendix 4 of the RR according to the most recent version of Recommendation ITU-R S.1503

OEA/Ser.L/XVII.4.2.33 CCP.II-RADIO-33/doc. 4858-7-I/19 11 April 2019 Original: English


AGENDA ITEM 7, ISSUE I




CCPII-2019-33-4358r1_i 30.05.19 224

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Issue I Modified regulatory procedure for non-GSO satellite systems with short-duration missions.

BACKGROUND:

In recent years, an increasing number of academic institutions, amateur satellite organizations and government agencies have been developing non-GSO satellite systems with short duration missions using nano and picosatellites. The use of these types of satellites has presented various regulatory challenges, including difficulties for the notifying administrations to provide accurate RR Appendix 4 orbital characteristics at the beginning of the development cycle and, in some instances, not even prior to the launch of the satellites. At WRC-15 a proposal for a new agenda item for WRC-19 “to consider modifications to the regulatory procedures for notifying satellite networks to accommodate nanosatellite and picosatellite missions” was submitted. WRC-15 decided not to include this as an item on the WRC-19 agenda, and concluded that this matter could best be dealt with by the ITU-R under the standing WRC agenda item 7. As a result, the ITU-R developed a method (I2) to address this issue that consists of modifications to the existing regulatory procedures for advanced publication and notification of satellite networks and systems that are not subject to Section II of RR Article 9 to facilitate the recording of non-GSO satellite systems with short-duration missions in the MIFR. This proposal assumes that the requirement of short duration missions could be accommodated within frequency bands not subject to coordination. However, it is understood that some of these frequency bands are already very crowded (e.g. space science missions in the frequency bands 2200-2290 MHz and 2025 – 2110 MHz). As a result, the frequency bands suitable for short duration missions should be carefully considered and every efforts should be made to avoid bands that are heavily used.

Supports: CAN, MEX MOD DIAP/7(I)/2

9.1 Before initiating any action under Article 11 in respect of frequency assignments for a satellite network or a satellite system not subject to the coordination procedure described in Section II of

Article 9 below, an administration, or one10 acting on behalf of a group of named administrations, shall send to the Bureau a general description of the network or system for advance publication in the International Frequency Information Circular (BR IFIC) not earlier than seven years and preferably not later than two years before the planned date of bringing into use of the network or system (see also No. 11.44). The characteristics to be provided for this purpose are listed in Appendix 4. The notification information may also be communicated to the Bureau at the same time, but shall be considered as having been received by the Bureau not earlier than six four months after the date of publication of the advance publication information. (WRC-1519)

Reasons: to reduce period between the date of publication of the advance publication information (API) and the earliest possible date of receipt for notification information. Supports: CAN, MEX MOD DIAP/7(I)/3

9.2B On receipt of the complete information sent under Nos. 9.1 and 9.2, the Bureau shall

publish11 it in a Special Section of its BR IFIC within three two months. When the Bureau is not in a position to comply with the time limit referred to above, it shall periodically so inform the administrations, giving the reasons therefor. (WRC-200019)

Reasons: to reduce period between the receipt of the API and its actual publication in the BR IFIC. Supports: CAN, MEX MOD DIAP/7(I)/4 _______________

9.3 If, upon receipt of the BR IFIC containing information published under No. 9.2B, any administration believes that interference which may be unacceptable may be caused to its existing or planned satellite networks or systems, it shall within four months of the date of publication of the BR IFIC

communicate to the publishing administration its comments ADD XX on the particulars of the anticipated interference to its existing or planned systems. A copy of these comments shall also be sent to the Bureau. Thereafter, both administrations shall endeavour to cooperate in joint efforts to resolve any difficulties, with the assistance of the Bureau, if so requested by either of the parties, and shall exchange any additional relevant information that may be available. If no such comments are received from an administration within the aforementioned period, it may be assumed that the administration concerned has no objections to the planned satellite network(s) of the system on which details have been published. (WRC-19)

A.2.a the date (actual or foreseen, as appropriate) of bringing the frequency assignment (new or modified) into use

For a frequency assignment to a GSO space station, including frequency assignments in Appendices 30, 30A and 30B, the date of bringing into use is as defined in Nos. 11.44B and 11.44.2 For a frequency assignment to a non-GSO satellite system with a short-duration mission, the date of bringing into use is as defined in draft new Resolution [A7(I)-NGSO SHORT DURATION] (WRC-19) Whenever the assignment is changed in any of its basic characteristics (except in the case of a change under A.1.a, the date to be given shall be that of the latest change (actual or foreseen, as appropriate) Required only for notification

DRAFT NEW RESOLUTION [A7(I)-NGSO SHORT DURATION] (WRC-19)

Modified regulatory procedures for the processing of frequency assignments to non-GSO satellite

networks or systems identified as short-duration mission1 under Articles 9 and 11


considering

a) that some non-GSO satellites with short-duration missions to date have been operating for their entire mission duration without being notified or recorded;

b) that successful and timely development and operation of non-GSO satellite networks or systems with short-duration missions may require regulatory procedures which take account of the short development cycle, the short lifetimes and the typical missions of such satellites, and therefore the application of certain provisions of Articles 9 and 11 of the Radio Regulations may need to be adapted to take account of the nature of these satellites;

c) that these satellites typically have a short (one to two years) development time and are low cost, often using off-the-shelf components;

d) that the operational lifetime of these satellites generally ranges from several weeks up to not more than three years;

e) that non-GSO satellites with short-duration missions are being used for a wide variety of applications, including remote sensing, space weather research, upper atmosphere research, astronomy, communications, technology demonstration and education, and therefore may operate under various radiocommunication services;

f) that advances in the field of satellite technology have resulted in non-GSO satellites with short-duration missions becoming a means for developing countries to become involved in space activities,

considering further

a) that the application of provisions of Articles 9 and 11 to frequency assignments to non-GSO satellite networks or systems identified as short-duration mission as prescribed in this Resolution should not adversely or otherwise affect the regulatory treatment of other systems;

b) that the application of any modified regulatory procedure should not change the sharing status with respect to networks and systems not applying the modified regulatory procedure, both terrestrial and space, in frequency bands which may be used by non-GSO satellite systems with short-duration missions,

recognizing

a) that Resolution ITU-R 68 seeks to improve awareness and increase knowledge on existing regulatory procedures for small satellites;

b) that, even though satellite mass and size are not relevant from a frequency management perspective, the small mass and small dimensions of these satellites have been some of the major contributors to their success amongst new space-faring nations;

1 For the purpose of this Resolution, the definition of non-GSO satellite systems identified as short-duration missions is contained in resolves 4 and 5 of this Resolution.

231 CCPII-2019-33-4358r1_i 30.05.19

c) that all the non-GSO satellite networks or systems operating in bands not subject to Section II of Article 9 are, irrespective of the period of validity of their associated frequency assignments, subject to No. 9.3 and its process for resolution of difficulties;

d) that non-GSO satellite systems with short-duration missions are not be used for safety-of-life services,

noting

a) Report ITU-R SA.2312 on “Characteristics, definitions and spectrum requirements of nanosatellites and picosatellites, as well as systems composed of such satellites”;

b) Report ITU-R SA.2348 which contains descriptions of current regulatory practices relating to space network notification of such satellites,

resolves

1 that this Resolution shall apply only to non-GSO networks or systems identified by the notifying administration as short duration mission;

2 that non-GSO satellite networks or systems identified as short-duration mission operating under any space radiocommunication service in bands not subject to the application of Section II of Article 9 shall be subject to the provisions of the Radio Regulations with the exceptions stipulated in the Annex to this Resolution;

3 that non-GSO satellite networks or systems identified as short-duration mission operating in frequency bands allocated to satellite services shall operate in accordance with the relevant conditions of the allocated satellite service;

4 that non-GSO satellite networks or systems identified as short-duration mission using spectrum allocated to the amateur-satellite service shall operate in accordance with the definition of the amateur-satellite service as contained in Article 25 of the Radio Regulations;

5 that the total number of satellites in a non-GSO satellite network or system identified as short-duration mission shall not exceed [3] [ten/TBD] satellites;

6 that the maximum period of operation and validity of frequency assignments of a non-GSO satellite network or system identified as short-duration mission shall not exceed three years from the date of bringing into use of the frequency assignments (see the Annex to this Resolution for the definition of date of bringing into use for such network or system), without any possibility of extension, after which the recorded assignments shall be cancelled;

7 that for the purpose of this Resolution, a non-GSO satellite network or system identified as short-duration mission shall have a single launch date associated with the first launch (in the case of systems with multiple launches) and that launch date shall be defined as the date on which the first satellite of the non-GSO satellite network or system with a short-duration mission is placed into its notified orbital plane,


1 to establish, as soon as possible, proper means to identify the non-GSO satellite networks or systems with short-duration missions subject to this Resolution;

2 to expedite the online publication of notices for such networks or systems, in addition to the normal publication of notices;

3 to provide the necessary assistance to administrations in the implementation of this Resolution,


1 to avoid frequency bands heavily used when assigning frequencies to a non-GSO satellite network or system with a short duration mission;

232 CCPII-2019-33-4358r1_i 30.05.19

2 to exchange information associated with non-GSO satellite networks or systems identified as short-duration missions and to make every possible effort to resolve interference that may be unacceptable to existing or planned satellite networks or systems, including those with short-duration missions;

3 to disseminate information on non-GSO satellite networks or systems identified as short-duration missions in accordance with the provisions of Resolution ITU-R 68;

4 to provide their comments on the application of No. 9.3, upon receipt of the International Frequency Information Circular (BR IFIC) containing information published under No. 9.2B, as soon as possible within a period of four months from the date of publication of the (BR IFIC) and to communicate with the notifying administration, with copy to the Bureau, these comments on the particulars of the potential interference to its existing or planned systems.

ANNEX TO DRAFT NEW RESOLUTION [A7(I)-NGSO SHORT DURATION] (WRC-19)

Application of the provisions of Articles 9 and 11 for non-GSO satellite networks and systems identified as short-duration missions

1 The general provisions of the Radio Regulations shall apply to non-GSO satellite networks or systems identified as short-duration mission with the following exceptions/additions/amendments.

2 That when submitting advance publication information under No. 9.1, administrations shall submit the best estimated orbital characteristics (Appendix 4 data item A.4.b.4) known at the early development time of the satellite project.

3 In the application of No. 9.1, the notification information cannot be communicated to the Bureau at the same time, and can only be submitted after the launch of a satellite in the case of a network or the first satellite in the case of a system with multiple launches.

4 Notices relating to non-GSO satellite networks or systems identified as short-duration mission shall be communicated to the Bureau only after the launch of a satellite in the case of a satellite network or the first satellite in the case of a system requiring multiple launches, and not later than two months after the date of bringing into use. This provision applies instead of No. 11.25 for frequency assignments to non-GSO satellite networks or systems with short-duration mission. Irrespective of the date of receipt of the notified characteristics of the non-GSO satellite network or system with a short-duration mission under this Resolution, the maximum period of validity of frequency assignments of this system shall not exceed the time limit in resolves 6 of this Resolution. At the expiry date of period of validity, as described in resolves 6 of this Resolution, the Bureau shall publish a suppression of the related Special Section.

NOTE: In developing the alternative application of RR No. 11.25 above it was recognized that it would be important to include a requirement for administrations to also submit a commitment to the Bureau stating that in case unacceptable interference caused by the short-duration mission system is not resolved, it shall undertake to eliminate the interference or reduce it to an acceptable level. It was further recognized that this commitment should be considered part of the complete information for the notice and should therefore be included as a new data item under Appendix 4.

5 In the application of No. 11.28 the Bureau shall make available on its website the complete information received instead of publication in the BR IFIC. Administrations may comment upon this information in accordance with No. 11.28.1.

6 In addition to the application of No. 11.36 the Bureau shall publish the characteristics of the system together with the findings under No. 11.31 in the BR IFIC and on its website within no more than four months from the date of receipt of complete information under No. 11.28. When the Bureau is not in a position to comply with the time-limit referred to above, it shall periodically so inform the notifying administration, giving the reasons therefor.

7 In the application of No. 11.44, the date of bringing into use of a non-GSO satellite network or system identified as short-duration mission shall be considered automatically as the launch date of a satellite

233 CCPII-2019-33-4358r1_i 30.05.19

in the case of a non-GSO satellite network or the first satellite in the case of a non-GSO satellite system requiring multiple launches (see resolves 7 of this Resolution).

8 No. 11.49 shall not apply to frequency assignments to non-GSO satellite networks or systems identified as short-duration mission.

Reasons: to specify exceptions/additions/amendments to the general provisions in Articles 9 and 11.

AGENDA ITEM 7, ISSUE J


(Document submitted by CITEL Member States) SGT-3 – Satellite services Coordinator: Brandon MITCHELL – USA Alternate Coordinator: Juan MASCIOTRA – ARG; Chantal BEAUMIER – CAN Rapporteur Agenda Item: Michelle CALDEIRA Alternate Rapporteur Agenda Item: Ángeles GALLEGO – MEX; [Carolina DAZA – COL]

235 CCPII-2019-33-4358r1_i 30.05.19

Agenda item 7: to consider possible changes, and other options, in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference, an advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks, in accordance with Resolution 86 (Rev.WRC-07) to facilitate rational, efficient, and economical use of radio frequencies and any associated orbits, including the geostationary-satellite orbit; Issue J – Pfd limit in Section 1, Annex 1 of RR Appendix 30 BACKGROUND Issue J deals with the possibility of the exceedance of the power flux-density (pfd) limit of −103.6 dB(W/(m2 · 27 MHz)) which was established for use in Regions 1 and 3 in order to protect BSS networks outside the coordination arc of ±9 degrees. In the case that an administration applies the relevant provisions of RR Article 23 to request the exclusion of its territory from the service areas of BSS networks of other administrations, such BSS networks of other administrations are not entitled to be protected within the territory of the objecting administration. According to the idea above, the pfd limit of −103.6 dB(W/(m2 · 27 MHz)) may be exceeded only within the national territory of the notifying administration providing that, on the border areas and other territory of another country, this pfd limit is not exceeded. Under WRC-19 agenda item 7 Issue J, two methods are provided. Method J1 proposes modifications to Section 1, Annex 1 of RR Appendix 30 and Method J2 proposes no changes to the Radio Regulations. DRAFT INTER-AMERICAN PROPOSAL Supports: CAN, MEX NOC: DIAP/7(J)




ANNEX 1 (REV.WRC-15)

Limits for determining whether a service of an administration is affected by a proposed modification to the Region 2 Plan or by a proposed

new or modified assignment in the Regions 1 and 3 List or when it is necessary under this Appendix to seek

the agreement of any other administration25

Given that WRC-19 Agenda Item 7, Issue J is a Regions 1 and 3 only issue, no change is proposed for Region 2. Furthermore, any changes made to the Radio Regulations under WRC-19 agenda item 7 Issue J must not impact the Region 2 Plan in Appendix 30.

236 CCPII-2019-33-4358r1_i 30.05.19

Reasons: In order to protect the services offered in Region 2, changes that are made only in Regions 1 and 3 should not modify the procedural conditions for Region 2 within the framework of the matter. Therefore, it is proposed not to implement any change (NOC) that could affect the procedures in Region 2.

238 CCPII-2019-33-4358r1_i 30.05.19

Agenda Item 9.1, Issue 9.1.1: to study possible technical and operational measures to ensure coexistence and compatibility between the terrestrial component of IMT (in the mobile service) and the satellite component of IMT (in the mobile service and the mobile-satellite service) in the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz where those frequency bands are shared by mobile service and the mobile-satellite service in different countries, in particular for the deployment of independent satellite and terrestrial components of IMT and to facilitate development of both the satellite and terrestrial components of IMT BACKGROUND The basis for Agenda Item 9.1, Issue 9.1.1 originated at WARC-92 with the addition of No. 5.388. This footnote identified certain frequencies for use by both satellite (MSS), and terrestrial (MS) in what are now called International Mobile Telecommunications (IMT). The frequency ranges in the footnote are 1 885-2 025 and 2 110-2 200 MHz. Within these broader frequency ranges, the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz are allocated to the fixed, mobile, and mobile-satellite services on a co-primary basis. Both the satellite and terrestrial components of IMT have already been deployed or are being considered for further deployment within the 1 980-2 010 MHz and 2 170-2 200 MHz frequency bands as noted in Resolution 212 (WRC-15). Resolution 212 (Rev. WRC-15) further notes that it is not feasible to implement the terrestrial and satellite components of IMT on the same frequency and in the same geographical area is not feasible unless techniques such as use of an appropriate guard band or other mitigation techniques are applied to ensure the coexistence and compatibility of the terrestrial and satellite components of IMT. Finally, it invites the ITU-R to study possible technical and operational measures to ensure coexistence and compatibility between MS in one country and MSS in another country. This agenda item seeks to identify and study only technical and operational measures. It does not include any regulatory studies and is confined to seeking those technical and operational measures that can be used to obtain coexistence and compatibility between the terrestrial and satellite components of IMT specified within ITU-R Recommendations. Only the results for such systems specified as part of ITU-R Recommendations should be included in the conclusions of the studies undertaken by the ITU-R for this Agenda Item and used as a basis for decisions made at WRC-19. ITU-R WP 5D is responsible for the studies related to the protection of the terrestrial component of IMT, taking into account the technical and operational characteristics of satellite systems provided by ITU-R WP 4C. Similarly, the ITU-R WP 4C is responsible for the studies related to the protection of the satellite component of IMT, taking into account the technical and operational characteristics of terrestrial IMT systems provided by ITU-R WP 5D. An ITU-R report or recommendation will be prepared based on the studies. CPM text will be jointly developed by these two working parties. Prior ITU-R studies have focused on co-existence and compatibility of terrestrial and satellite components of IMT within the same geographic area. WRC-19 Agenda Item 9.1, Issue 9.1.1 is focused on studying the co-existence and compatibility when the two are deployed in different countries. Several compatibility studies have been performed by the ITU-R under AI 9.1.1 for adjacent geographic areas of neighboring countries. The compatibility studies display a wide range of results that depend on the deployment scenarios and the propagation characteristics assumed for the satellite and terrestrial components of IMT as well as the characteristics of the satellite and terrestrial IMT systems. As part of these studies, several technical and operational measures for both the satellite and the terrestrial component of IMT have also been identified and studied. The results of the study of these technical and operational measures indicate that the compatibility of the terrestrial and satellite IMT component operation in adjacent countries can be achieved through application of some of these technical and operational measures depending on the actual deployment characteristics of the two systems involved. Administrations can flexibly adopt a variety of these measures based on actual system characteristics during the bilateral

239 CCPII-2019-33-4358r1_i 30.05.19

coordination processes currently available as part of the existing ITU-R Radio Regulations. This flexibility should be maintained, as any change to the Radio Regulations (which would be outside the terms of reference for this agenda item), would limit this flexibility. The bands 1 980-2 010 MHz and 2 170-2 200 MHz overlap with parts of existing commercial mobile bands in some countries in the frequency ranges 1 850-1 920 / 1 930-2 000 MHz, 1 710-1 780 / 2 110-2 180 MHz and 2 000-2 020 / 2 180-2 200 MHz (see ITU-R Recommendation M.1036), in which terrestrial IMT systems exist or are expected to be deployed. The band 2 000-2 020 / 2 180-2 200 MHz is also licensed for MSS use in some countries. CITEL PCC.II has conducted a survey entitled “Request for information about the current and planned use of the bands 1 980-2 025 MHz and 2 160-2 200 MHz by the OAS/CITEL administrations for terrestrial and satellite services” in February 2015 (see Decision PCC.II/DEC. 173 (XXV-15) in CCP.II-RADIO/doc. 3857/15 rev.1)4, which may be relevant for the studies under this issue. Also, CITEL adopted a recommendation on the frequency arrangement for the use of the 1 710-1 780 / 2 110-2 180 MHz band for broadband mobile services, recommending CITEL administrations that plan to use this spectrum do so by adding additional contiguous bandwidth as an expansion of the existing bands in the 1 710-1 770 / 2 110-2 170 MHz or 1 710-1 755 / 2 110-2 155 MHz in some countries (see Decision PCC.II/REC. 43 (XXIII-14) in CCP.II-RADIO/doc.3597 /14 rev.1). ITU-R studies in response to this agenda item indicate that while compatibility of the terrestrial and satellite components of IMT in adjacent countries may require certain technical and operational measures, these measures are varied and may not be universally applicable to all possible cross-border cases. Several technical and operational measures have been identified. Administrations presently have the flexibility to adopt a variety of such measures, based on actual system characteristics and confidential information, during the bilateral coordination processes, and this flexibility should be maintained. A change to the Radio Regulations would limit the present flexibility for deployments by individual countries.

Implementation of International Mobile Telecommunications in the frequency bands 1 885-2 025 MHz and 2 110-2 200 MHz

The World Radiocommunication Conference (Geneva, 2015Sharm-el-Sheikh, 2019),

considering

a) that Resolution ITU-R 56 defines the naming for International Mobile Telecommunications (IMT);

b) that the ITU Radiocommunication Sector (ITU-R), for WRC-97, recommended approximately 230 MHz for use by the terrestrial and satellite components of IMT;

c) that ITU-R studies forecast that additional spectrum may be required to support the future services of IMT and to accommodate future user requirements and network deployments;

d) that ITU-R has recognized that space techniques are an integral part of IMT;

e) that, in No. 5.388, WARC-92 identified frequency bands to accommodate certain mobile services, now called IMT,

noting

a) that the terrestrial component of IMT has already been deployed or is being considered for deployment in the frequency bands 1 885-1 980 MHz, 2 010-2 025 MHz and 2 110-2 170200 MHz; b) that both the terrestrial and satellite components of IMT have already been deployed or are being considered for deployment in the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz;

b) that both the terrestrial and satellite components of IMT have has already been deployed or are is being considered for deployment in the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz;

c) that the availability of the satellite component of IMT in the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz simultaneously with the terrestrial component of IMT in the frequency bands identified in No. 5.388 would improve the overall implementation and the attractiveness of IMT,

noting further

a) that cd) that ITU-R studies have identified technical and operational measures that may be implemented to allow co-existence and compatibility between co-coverage, co-frequency deployment of independent satellite and terrestrial IMT components is not feasible unless techniques, such as the use of an appropriate guardband or other mitigation techniques, are applied to ensure coexistence and compatibility between the terrestrial and satellite components of IMT;

b) that, of IMT when the satellite and terrestrial components of IMT are deployed in the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz in adjacent geographicalgeographic areas, while ensuring that such measures do not constrain the operation of these components. technical or operational measures may need to be implemented to avoid harmful interference, and further studies by ITU-R are required in this regard;

c) that some difficulties have been raised in addressing potential interference between the satellite and terrestrial components of IMT;

d) that Report ITU-R M.2041 addresses sharing and adjacent band compatibility in the 2.5 GHz band between the terrestrial and satellite components of IMT-2000,

resolves

that administrations which implement IMT:

a) should make the necessary frequencies available for system development;

241 CCPII-2019-33-4358r1_i 30.05.19

b) should use those frequencies when IMT is implemented;

c) should use the relevant international technical characteristics, as identified by ITU-R and ITU-T Recommendations,

invites ITU-Radministrations

to study possible technical and operational measures to ensure coexistence and compatibility between the terrestrial component of IMT (in the mobile service) and the satellite component of IMT (in the mobile service and the mobile-satellite service) in the frequency bands 1 980-2 010 MHz and 2 170-2 200 MHz where those frequency bands are shared by the mobile service and the mobile-satellite service in different countries, in particular for the deployment of independent satellite and terrestrial components of IMT and to facilitate development of both the satellite and terrestrial components of IMT,

encourages administrations

1 to give due consideration to the accommodation of other services currently operating in these frequency bands when implementing IMT;,

2 to participate actively in the ITU-R studies in accordance with invites ITU-R above,


to include in his report, for consideration by WRC-19, the results of the ITU-R studies referred to in invites ITU-R above,

further invites ITU-R

to continue its studies with a view to developing suitable and acceptable technical characteristics for IMT that will facilitate worldwide use and roaming, and ensure that IMT can also meet the telecommunication needs of the developing countries and rural areas. Reasons: The studies responsive to this agenda item will be complete by WRC-19 and will document technical and operational measures to promote compatibility between the terrestrial and satellite components of IMT in different countries.

Agenda Item 9.1, Issue 9.1.7: Resolution 958 (Rev.WRC-15): to consider and approve the Report of the Director of the Radiocommunication Bureau, in accordance with Article 7 of the Convention, on the activities of the Radiocommunication Sector since WRC-15 on the urgent studies required in preparation for WRC-19 on the unauthorized operation of earth station terminals (Res. ITU-R 64 (RA-15)).

Background Information: The Radiocommunication Assembly (RA-15) approved Resolution ITU-R 64, titled “Guidelines for the management of unauthorized operation of earth station terminals”. The resolves of this resolution invited ITU-R study groups concerned:

1 to conduct studies to examine whether there is a need for possible additional measures in order to limit uplink transmissions of terminals to those terminals authorized in accordance with No. 18.1;

2 to study the possible methods that will assist administrations in managing the unauthorized operation of earth station terminals deployed within their territory, as a tool to guide their national spectrum-management program.

Resolution 958 (WRC-15) identifies topics requiring urgent study for inclusion in the Report of the Director for WRC-19. In the Annex to this resolution, Section 2 raises the issue of unauthorized operation of uplink terminals.

a) whether there is a need for possible additional measures in order to limit uplink transmissions of terminals to those authorized terminals in accordance with No. 18.1; and

b) the possible methods that will assist administrations in managing the unauthorized operation of earth station terminals deployed within its territory, as a tool to guide their national spectrum management programme, in accordance with Resolution ITU-R 64 (RA-15).

This issue concerns the operation of unlicensed uplink terminals in an administration’s territory. For some administrations, the use of these terminals causes interference into legitimate satellite service users as well as terrestrial systems. These administrations may not have the resources or technical capabilities to identify and geo-locate the unauthorized uplink terminals. An objective of this issue is to determine whether there is any need for regulatory measures to inhibit the use of unauthorized uplink terminals. So far, studies have shown that this issue can be resolved within the administration by methods not requiring modification of the Radio Regulations. Some administrations may require better spectrum management training and internal spectrum monitoring to identify unauthorized uplink transmissions. The development of ITU-R reports or handbooks may assist administrations in the management of their satellite spectrum resources to prevent or limit the unauthorized use of uplink terminals and enable the administration to locate and terminate the unauthorized transmissions. Article 18 of the Radio Regulations already addresses the licensing of uplink transmissions of terminals. In particular RR No. 18.1 states that “No transmitting station may be established or operated by a private person or by any enterprise without a licence issued in an appropriate form and in conformity with the provisions of these Regulations by or on behalf of the government of the country to which the station in question is subject.” Draft Inter-American Proposal:

Reasons:

Issue 2a) No change to Radio Regulations Articles, Appendices, Resolutions and/or Recommendations is required to solve this issue. This is a matter to be addressed mainly by initiatives taken under the spectrum licensing and enforcement regimes, which are controlled by the spectrum management authority in a national level.

Additionally, the collaboration between regulatory agencies and satellite operators, the improvement of satellite radiomonitoring capabilities, and/or the exchange of data generated by such facilities under the scope of International Cooperation (e.g. bilaterally or under a Memorandum of Understanding with ITU) are some examples of actions that can be taken under the current international regulatory framework, addressing the main problems faced by the administrations in this regard.

Issue 2b) Considering the results of the studies conducted during the last study period, several activities have been performed under ITU-R Study Group 1, especially in Working Party 1C, on the update and/or production of new reports, such as ITU-R SM.2182, SM.2424-0 and SM.2257-4. These reports provide the necessary guidance including information on facilities, techniques and study cases, including satellite radiomonitoring operations performed in major international events, assisting administrations to mitigate the 9.1.7 Issue 2b. The Radiocommunication Assembly Resolution ITU-R 64 (Guidelines for the management of unauthorized operation of earth station terminals) sufficiently addresses this issue. It shall be kept as a stable ITU-R Resolution during Radiocommunications Assembly 2019, in order to guarantee that Administrations and ITU Membership are continuously updated with latest technologies, techniques and further studies in this area, as a support for managing the unauthorized operation of earth station terminals deployed within their territory, and as a tool to guide their national spectrum-management programme.

Agenda Item 9.1/Issue 9.1.9: Resolution 162 (WRC 15) – Studies relating to spectrum needs and possible allocation of the frequency band 51.4-52.4 GHz to the fixed-satellite service (Earth-to-space).RESOLUTION 809 (WRC 15)

INTRODUCTION

Satellite systems are increasingly being used to deliver broadband services with high data rates to accommodate user demand and service expectations worldwide. Next-generation satellite networks are expected to provide data rate services from 100 Mbit/s to greater than 1 Gbit/s on a single channel to all users regardless of location. Satellite systems enable the immediate connection of many subscribers, irrespective of their location, to broadband and Internet backbone networks with just one launch, compared to a point-by-point roll-out. By implementing advanced technologies such as spot-beam antennas and high frequency reuse factors, HTS reach many times the throughput of traditional satellites using the same amount of allocated spectrum, which leads to the reduction of Gigabits per second (Gbit/s) costs. The limiting factor of HTS satellite networks is the amount of spectrum allocated to the forward link in the Earth-to-space segment (gateway-to-satellite link). Current HTS systems are mainly operated in Ka-band and use the Earth-to-space allocations for both user links and gateway links, which leads to the scarcity of spectral resources in this frequency band. In order to achieve higher data rates and improve the services provided to end-users, it is proposed to use the allocation to FSS (Earth-to-space) in the 50/40 GHz frequency bands for the gateway uplink (from gateway to space station) and Ka-band allocations to FSS (Earth-to-space) for the user uplink (from user terminals to space station). Therefore, the consideration of new primary allocations to the FSS in the frequency band 51.4-52.4 GHz (Earth-to-space) limited to FSS gateway links is required. The current frequency range of primary allocations to FSS (Earth-to-space) in the frequency bands 40/50 GHz in Regions 1, 2 and 3 is 42.5-43.5 GHz, 47.2-50.2 GHz and 50.4-51.4 GHz. The two FSS Earth-to-space allocations in the frequency bands 47.2-50.2 GHz and 50.4-51.4 GHz are almost contiguous, making these 4 GHz allocations suitable for operation of wideband carriers. The additional allocation of FSS (Earth-to-space) in the 51.4-52.4 GHz frequency band will allow access to 5 GHz of almost contiguous spectrum for the uplink communications; in addition, the 42.5 43.5 GHz allocation would enable a total of 6 GHz of spectrum for Earth-to-space communications. This situation will make it more suitable for the operation of FSS systems providing high data rate services worldwide with satisfactory availabilities. The consideration of all these aspects indicate that the additional allocation to the FSS being considered would be beneficial to make reliable broadband connections more accessible to communities through satellite communication regardless of their geographical location, as achieved by HTS. Background In preparation for WRC-19, Working Group 4A (WP 4A) of the ITU-R has carried out the studies on spectrum requirements and the possible allocation of the frequency band 51.4-52.4 GHz to the fixed-satellite service (FSS) (Earth-to-space). In response to Resolution 162 (WRC-15), WP 4A developed two Reports; one on spectrum needs for development of the FSS and the second one on sharing and compatibility between FSS and existing services. It is considered to make an allocation of the frequency band 51.4-52.4 GHz to the FSS (Earth-to-space), limited to FSS gateway links for geostationary orbit use while protecting currently allocated services in the same frequency band and in adjacent frequency bands.

247 CCPII-2019-33-4358r1_i 30.05.19

CITEL Member States support the studies carried out at the ITU-R Working Party 4A on sharing and compatibility studies to allow new primary allocation to the FSS in the frequency band 51.4-52.4 GHz (Earth-to-space), considering the protection of fixed and mobile services already allocated in this band.

CCPII-2019-33-4358r1_i 30.05.19 258

Agenda item 10: to recommend to the Council items for inclusion in the agenda for the following WRC, in accordance with Article 7 of the Convention, BACKGROUND: The operation of earth stations in motion (ESIM) that communicate with non-geostationary space stations in the fixed-satellite service is not new to the international regulatory framework. Footnote 5.527A allows the operation of earth stations in motion (ESIM) communicating with geostationary FSS networks, subject to compliance with Resolution 156 (WRC-15) in the frequency bands 19.7-20.2 GHz and 29.5-30.0 GHz. On the other hand, within the framework of Agenda Item 1.5, WRC-19 is expected to allow ESIM communicating with geostationary FSS networks to operate in all or parts of the frequency bands 17.7-19.7 GHz and 27.5-29.5 GHz In Europe, the operation of ESIM communicating with geostationary space stations in the fixed-satellite service is allowed in the bands 17.3-20.2 GHz, 27.5-27.8285 GHz, 28.4445-28.8365 GHz and 29.4525-30 GHz, and in the band 28.8365-28.9485 subject to compliance with sharing conditions with systems operating under primary terrestrial service allocations (see ECC Decision (13)01). In fact, in Europe the operation of land and maritime ESIM communicating with non-geostationary space stations in the fixed-satellite service is harmonized in the frequency bands 17.3-20.2 GHz, 27.5-29.1 GHz and 29.5-30.0 GHz (See ECC Decision (15)04). In addition, ECC Report 217 contains the studies – in particular the relevant sharing and compatibility studies for the co-existence of this kind of ESIM with other stations in services allocated in the aforementioned bands– supporting that ECC Decision. Canada proposes to carry out technical sharing studies between ESIM communicating with non-geostationary space stations in the fixed-satellite service and systems of other primary services in the frequency bands 17.7-20.2 GHz and 27.5-29.1 GHz and 29.5-30.0 GHz and to develop the appropriate technical and regulatory provisions to facilitate operation of such earth stations, while ensuring harmful interference is not caused to stations of the FSS, FS and other primary services. Uruguay proposes to carry out technical sharing studies between ESIM communicating with non-geostationary space stations in the fixed-satellite service and systems of other primary services in the frequency bands 17.7-19.7 GHz and 37.5-42.5 GHz (space-Earth) and 27.5-29.5 GHz and 47.2-50.2 GHz and 50.4-51.4 GHz (Earth-space) and to develop the appropriate technical and regulatory provisions to facilitate operation of such earth stations, while ensuring harmful interference is not caused to stations in the FSS, FS and other primary services. PREVIOUS/ONGOING STUDIES ON THE ISSUE: Technical and operational requirements for ESIM (which were referred to as earth stations on mobile platforms prior to WRC-15) operating in non-geostationary FSS systems in the frequency bands 17.3-20.2 GHz, 27.5-29.1 GHz and 29.5-30.0 GHz have been discussed in the ITU-R and are reflected in Report ITU-R S.2261. Studies on sharing between land and maritime ESIM in communication with non-geostationary space stations in the fixed-satellite service and terrestrial systems were carried out on a regional basis in the CEPT.

AGENDA ITEM 10 (B) “SPACE WEATHER SENSORS”



CCPII-2019-33-4358r1_i 30.05.19 263

Agenda item 10: to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, in accordance with Article 7 of the Convention. BACKGROUND: The Agenda Item 10 is a standing item on every World Radiocommunication Conference (WRC) agenda and its purpose is to recommend items to the Council for inclusion in the next WRC, as well as possible agenda items for future WRCs. WRC-19 Resolution 811 (WRC-15) addressed some preliminary agenda items for the WRC-23 between then the issue 2.3 which deals of the technical and operational characteristics, spectrum requirements and appropriate radio service designations for space weather sensors in accordance with Resolution 657 (WRC-15). A variety of physical phenomena associated with space weather can affect a number of services and infrastructure at the Earth’s surface, airborne, or space-borne in Earth orbit and disturbances in the ionosphere and atmosphere have important impacts on radio communication, satellite navigation systems and atmospheric drag experienced by LEO satellites, including the International Space Station, Radionavigation Satellite Service (RNSS) signals, which are used for a growing number of precision positioning, navigation, and timing applications; Space weather observations are critical to monitor and forecast the occurrence and probability of space weather disturbances (e.g. geomagnetic storms and substorms), to drive hazard alerts when disturbance thresholds are crossed, to maintain awareness of current environmental conditions, to determine climatological conditions for the design of both space-based systems (i.e., satellites and astronaut safety procedures) and ground-based systems (i.e., electric power grid protection and air traffic management), to develop and validate numerical models of space weather drivers, and to conduct research that will enhance our understanding of the Sun and Earth’s extended atmosphere. To address the requirements established in Resolution 657 (WRC-15), the ITU-R Working Group 7C has developed Report ITU-R RS.[Space_Weather_Sensors] – Technical and operational characteristics of RF-based space weather sensors5. This ITU-R Report documents the information called for by Resolution 657(WRC-15) to support studies to be performed under a possible agenda item on space weather at WRC-23. This Report also includes an assessment of potentially applicable radio services to the space weather sensor applications.

AGENDA ITEM 10 (C) “SUB-ORBITAL VEHICLES”



CCPII-2019-33-4358r1_i 30.05.19 269

Agenda Item 10: to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, in accordance with Article 7 of the Convention.

Background WRC-15 adopted Resolution 763 (WRC 15) to deal with stations on board suborbital vehicles. It was resolved to conduct studies during the WRC-19 study cycle:

to identify any required technical and operational measures, in relation to stations on-board suborbital vehicles, that could assist in avoiding harmful interference between radiocommunication services.

to determine spectrum requirements and, based on the outcome of those studies, to consider a possible future agenda item for WRC-23.

Further, in 2015 the ITU-R formulated Question ITU-R 259/5, "Operational and radio regulatory aspects for planes operating in the upper level of the atmosphere." Studies in the framework of that Question are related to Resolution 763 (WRC-15). In particular, decides 3 of the Question asks, "What radio links will be required to support space planes’ operations and under what radiocommunication service definition will they fall?" There are planned developments for sub-orbital flight based on various types of technologies and vehicles. The approaches vary between those using a single vehicle and those that use a launch vehicle that carries the spacecraft up to an intermediate height before releasing the spacecraft to accelerate away and into a suborbital spaceflight. The ITU-R performed technical and operational analyses of stations on-board suborbital vehicles including:

an evaluation of the regulatory provisions that may require additions or modifications; and identification of the potential need for spectrum to support communications and surveillance in

space, without changing the existing use of the space operations service.

In addition, the analyses examined link budgets and Doppler shift for suborbital vehicles using existing ICAO standardized radiocommunication systems and technologies. The studies concluded that, while no new spectrum allocations are necessary, a WRC-23 agenda item is necessary to modify definitions to ease introducing sub-orbital vehicle radiocommunications.

Agenda Item 10: to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, in accordance with Article 7 of the Convention.

Introduction

This contribution discusses the concept of space-based VHF voice communication and proposes to consider a future WRC-23 agenda item to enable the appropriate study activity within ITU-R WP 5B regarding the potential of an AMS(R)S allocation in the 118 to 137 MHz frequency band.

Discussion

In order to apply radar-like or other similar reduced separation minima over oceanic and remote areas, appropriate surveillance and communications are required. In 2015, the World Radiocommunication Conference (“WRC-15”) allocated the frequency band 1087.7 – 1092.3 MHz for reception of aircraft Automatic Dependent Surveillance – Broadcast (“ADS-B”) messages by space stations. Following WRC-15, the space-based ADS-B services are been implemented via the fully completed satellite constellation. Space-based ADS-B is expected to perform in the same manner as terrestrial ADS-B sensors without any need for aircraft avionics modification.

However, appropriate communication means is still an issue for oceanic and remote areas, and there is currently no suitable solution to provide Very High Frequency (“VHF”) voice services over these areas. Hence, the proposed consideration of a potential solution using VHF radio relay installed onboard satellites (“space-based VHF”), which would be an effective complimentary communication service to the space-based ADS-B. The concept is intended to provide VHF capability in remote areas and oceanic regions where normal VHF coverage is non-existent. Moreover, it is intended to be a complimentary extension to terrestrial VHF coverage where possible.

Currently there is no practical and cost-effective solution to provide VHF voice services over oceanic and some remote areas. Although High Frequency (“HF”) voice, satellite voice (“SATVOICE”) and controller-pilot data link communications (“CPDLC”) may be used in lieu of VHF voice, these technologies are currently not considered as direct controller-pilot communications (“DCPC”) fully capable for supporting radar-like or other similar reduced separation minima (e.g. 3, 5 or 10 NM). Moreover, not all aircraft are equipped with SATVOICE and/or CPDLC. Whereas, VHF voice communications relay would meet the required communication performance (“RCP”) for reduced separation minima, without modification to aircraft equipment.

Considering the advancements in satellite technologies as suitable communication equipment carriers, the potential for supporting radar-like or other reduced separation minima using space-based ADS-B in conjunction with space-based VHF voice is quite possible. Accordingly, the aviation community is beginning to work with various communications vendors to conduct design studies and trials/proof-of-concept for satellite mounted transceivers serving as VHF voice communication relay system.

Notwithstanding the above, the space-based VHF concept was discussed during the International Civil Aviation Organization (“ICAO”) Asia/Pacific Air Navigation Planning and Implementation Regional Group (“APANPIRG”) meeting held in September 2018 and the ICAO APANPIRG supported the operating concept for space-based VHF voice services (Conclusion APANPIRG29/18). Further to this, one administration contributed an input document to the 4th Meeting of the APT Conference Preparatory Group for WRC-19 (APT APG19-4) held in Busan, South Korea on 7 – 12 January 2019 to highlight the concept of space-based VHF voice communications that would require study in the ITU-R, and therefore consideration as a future Conference Agenda Item under AI 10.

In addition to the above, the recent ICAO FSMP WG-8 meeting held in January agreed on an amendment to the ICAO Position for WRC-19 to include the requirement for a future WRC agenda item. Therefore, this
