April 28, 2016, the Indian Space Research Organization (ISRO) successfully launched the

seventh and final spacecraft for the Indian Regional Navigation Satellite System (IRNSS). The

satellite, IRNSS-1G, was placed into orbit by a Polar Satellite Launch Vehicle (PSLV-C33).


PSLV-C33 with final IRNSS satellite lifts off

The prime minister of India, Narendra

Modi, watched the launch and

“heartily thanked and congratulated”

all the scientists and ISRO team for

completing the IRNSS constellation,

which he dedicated to the nation as

“NavIC” (Navigation Indian

Constellation).

After separation from PSLV-C33, the

solar panels of IRNSS-1G were

deployed automatically. ISRO's

Master Control Facility at Hassan,

Karnataka took over the control of the

satellite. After few orbit manoeuvres

the satellite is positioned in

geostationary orbit at 129.5 degrees

East longitude.

IRNSS is an independent regional

navigation satellite system designed

to provide position information in the

Indian region and 1,500 kilometres

around the Indian mainland.

IRNSS provides two types of services:

Standard Positioning Services (SPS), available to all users and

Restricted Services (RS), provided to authorized users.

A number of ground facilities responsible for satellite ranging and monitoring, generation

and transmission of navigation parameters, etc., have been established in eighteen locations

across the country. The successful launch of IRNSS-1G signifies the completion of the

IRNSS constellation.

AAI has taken up this pilot project in collaboration with the US-India Aviation Cooperation Programme

(ACP), US Trade and Development Agency (USTDA) grant. The GBAS will support future demand at the

Chennai international airport by reducing delays, operational costs and increasing traffic throughput.

GBAS Remains Operational During Winter Storm Jonas (Excerpts from SATNAV NEWS Volume 56 modified for GAGAN)

Ground Based Augmentation System (GBAS)

remained operational at Newark International

Airport during winter storm Jonas. Newark and

surrounding airports (Kennedy and LaGuardia) ILS

systems were out of service for high snow

conditions; however, the Newark GBAS remained

operational throughout the snowstorm. CAT I

GBAS operations are now standard operations at

Newark and Houston airports. As of December

2015 a total of 2,394 GLS approaches had been

conducted at Newark, NJ and Houston, TX by

United Airlines, Delta Air Lines and international

airlines (Lufthansa, Cathay Pacific, British Airways,

and Emirate Airlines). GLS equipage grows with the

implementation of new Boeing and Airbus aircraft

capable of GLS approaches.

The GBAS program achieved a milestone in October

2015 with the approval of an important

modification (Block II update) of the previously

approved GBAS CAT I system (Honeywell SLS-4000

Block I) configuration. This modification will

enhance system availability through an updated

signal deformation monitoring algorithm and more

efficient multipath masking techniques. An option

to leverage use of WAAS real-time ionospheric

monitoring was also approved as part of this block

update; this option may provide a path to

approving auto land capabilities.

The primary focus of the FAA GBAS program for

the past year has been validation of the ICAO

Standards and Recommended Practices (SARPS)

for GBAS Approach Service Type D (GAST-D)

requirements. GBAS GAST-D supports Cat II/III

approach and landing operations. The ICAO target

date for final SARPS review and acceptance is

planned for Summer 2016. In parallel to the final

ICAO requirements validation efforts the FAA and

Honeywell have started the system design

approval (SDA) process for the Honeywell SLS-

5000 system, which will be Honeywell’s GAST-D

capable GBAS system. The kickoff meeting was

held at Honeywell’s Coon Rapids, MN facility in

January 2016. The SLS-4000 Block II design

approval will serve as the GAST-D design baseline

with the GAST-D ICAO SARPS as the approval

basis. Work done under the FAA’s GAST-D

prototyping contract with Honeywell which ended

in May 2015 will contribute to the total SDA effort.

The next International GBAS Working Group

(IGWG) will be hosted by the Norwegian Service

Provider in Oslo, Norway April 18-21, 2016. The

IGWG is chaired by FAA and EUROCONTROL with

over 100 participants from twelve nations,

international service providers, industry, airlines

and aircraft manufacturers attend the meeting

and working sessions, which focus on GBAS

development and implementation activities.

GAGAN to Provide Navigational Support Systems to Indian Railways

“ISRO will provide satellite-generated information to the railways through space

technology-based tools that will provide safety at unmanned level crossings,” ISRO

Chairman A S Kiran Kumar told in reply to a question on how will ISRO help the

Railways in using the navigational support system. “There are host of requirements

for using GAGAN in railways. We are providing some solutions,” Kumar said.

Elaborating on it, Kumar said that at some places the railway tracks are under

stress. If water accumulation happens, then based on digital elevation model data,

other host of information which they generate, can be given.

“There is specific information provided for aligning the railway tracks, particularly in

mountainous regions, and also identifying tracks which are most stable when you

are going through tunnels. In all these things, space technology is useful,” he said.

With the use of GAGAN system, a train would know the location of any unmanned

level crossing ahead of it. As the train approaches the unmanned level crossing, the

train’s hooter triggers automatically well before reaching it. Similarly a hooter

installed at the level crossing is also triggered to alert the people at the level

crossing, using satellite link.

GAGAN system design is primarily based on WAAS 8/9.2. Whenever any anomalies

are observed in the GAGAN system operational build, the same are mitigated by

modification of build with the support of System designer.

In the process of mitigation of certain system anomalies, on 16th May 2016, Raytheon

delivered an updated software build N3.027LN addressing one Hazard record #13,

namely DU count which was inherited from WAAS baseline 8/9.2. Also, the GEO

transponder offset values for GSAT 8 & GSAT 10 were updated as per current OCXO

values of GEO transponder. Control loop lock fault time for L5 is modified in the new

software build.

Upgraded software has been validated by AAI GAGAN Team during 30 days stability

test from 26th May 2016 to 24th June 2016. Evaluated the GAGAN performance on

daily basis and observed system performance satisfactory and addressed anomalies

are resolved.

All GAGAN subsystems were used during the Stability Test, including the INLUS-RFU

and GEO subsystems. The stability test included a series of switch over tests where

single subsystems were taken offline to demonstrate that the system correctly switches

over to a redundant component.

The stability test demonstrated that the software does not have any latent defects

which cause a sub-system to fail.

Aviation case study: Landing with satellite navigation (Excerpts from www.egnos-portal.eu modified for GAGAN)

Issue

Satellite navigation offers a means of global navigation, available 24/7 in all weather

conditions. Although GPS was designed for military purposes, these features rapidly

attracted the attention of the civil aviation community. They saw its potential for

navigating and approaching any runway around the globe compared to fully relying on

an airport’s local ground infrastructure.

GPS was therefore rapidly welcomed and used for en route navigation, or at least as a

complementary means of navigation.

For landing aircraft, the situation was quite different. System requirements are far

more stringent. The system has to be particularly accurate and reliable. For example

the pilot has to be informed within a few seconds when system performances are

degraded and must not be used for navigation. Such satellite navigation aviation

requirements are defined by the International Civil Aviation Organisation (ICAO) as

seen in the table below.

15

Aviation case study: Landing with satellite navigation (Excerpts from www.egnos-portal.eu modified for GAGAN)

As the performance of GPS is not fixed, the

service cannot be guaranteed and there is no

feature to alert the user in case of a failure

that impacts the quality of the positioning

measurement and consequently the safety of

the user. This restricts the use of GPS as an

instrument to assist in aircraft landing

operations by imposing important safety

buffers to compensate for the lack of

precision.

The EGNOS solution

The EGNOS ground infrastructure

continuously monitors GPS performance for

all of the European Union and beyond and

provides the user with error corrections,

considerably increasing the navigation

accuracy of the signal. In addition, EGNOS

is able to detect GPS satellite faults, to assign

a confidence level to the data transmitted to

a user and to provide timely warnings when

GPS or its data should not be used for

navigation. Satellite navigation therefore

becomes within reach for Instrument Flight

Rules. To formalise it, EGNOS was certified

by civil aviation authorities and was officially

declared as appropriate for civil aviation

landing (APV) in 2011.

The first commercial operation using a final

approach with EGNOS was the Trislander

aircraft operated by Aurigny Air Services, a

regional airline operating connection flights

between the Channel Islands and the UK and

France, from December 2011 onwards.

The US WAAS system provides similar

capabilities for the North American region.

The impact is therefore sizeable. Aircraft will

be able to land in all locations where

adequate procedures are published, without

requiring a huge investment in airport

equipment and maintenance.

Approach operations will be less constrained

by ground equipment features; they will be

more precise, increasing airport runway

capacity and overall airport efficiency.

General aviation, business jet services and

regional airlines have rapidly identified the

benefits of such use of the

technology. Avionics equipment

manufacturers are already proposing

EGNOS-enabled equipment and the

retrofitting of GPS equipment with EGNOS

capability.

The commercial aviation sector is also

joining the club. For example Airbus is

equipping its A350 XWB with a satellite-

based augmentation system (SBAS) receiver,

providing their customers with the capability

of landing without navigation ground

infrastructure and providing a geometric

vertical guidance, free of temperature and

barometric setting errors.
