EUMETCast System Overview

3Slide: 3

DVB-S2 Implementation, testing

System Integration • Complete integrated system including platform,

uplink service and transponder capacity was available mid June, with test data to users

• Verification testing• Started January, uncovered several issues regarding

redundancy• Performance issues related to redundancy switches

solved• Completed end of May

4Slide: 4

DVB-S2 Implementation, testing

EUMETCast Platform V&V • “power testing” in June for 4 weeks• Uncovered various performance issues related to

multicast in a real-time system, key areas are: • Storage system (non-blocking I/O)• Network (MC routing/switching)• Redundancy (lossless, fast)

• All issues were resolved step-by-step, with acceptable performance impact

5Slide: 5

DVB-S2 Implementation, testing

EUMETCast System V&V (incl. uplink and satellite)• “end to end testing” Mid July for 4 weeks• All redundancies activated and impact

characterised, including station switchover• Pilot users involved• Finally all remaining performance issues eliminated

(packet losses, delays due to storage performance)• Stability phase 1–13 August

6Slide: 6

Service V&V and Pilot Users, results

• Link Margin• Target availability 99.98% yearly,

equivalent to >4-5 dB clear sky link margin• In core of footprint DVB-S downlink margin is

higher than DVB-S2, but DVB-S2 uplink margin is better, thanks to ALC (Automatic Level Control) and backup uplink station

• Lower signal level in centre of footprint, same or higher outside (especially in the East)

• Link margin very sensitive to alignment and LNB used

Service V&V and Pilot Users, results

• Symbolrate 30MS/s vs. 33 MS/s• 30 MS/s provides 0.5 dB higher link margin but

10% lower data rate capacity• Planned link budget was fully achieved with 33

MS/s (with margin) 33 MS/s was operationally selected

• ISI (Input Stream Identifier)• ISI=1 is selected for a reason:

All tested receivers cannot receive error-free multiple streams (BS, HVS) if different ISI values are used

DVB-S2 documentation

• All migration information available on

http://www.eumetsat.int/website/home/TechnicalBulletins/EUMETCast/DAT_2082113.html

• The DVB-S2 WEB page is being frequently updated with latest information

• Static information will be inserted into TD 15• Will be merged into the generic EUMETCast pages

14Slide: 14

User Experience

• Receiver upgrade relatively easy for DVB routers, after a learning curve dealing with multicast networking

• USB and PCI/PCIE cards recently provide low price alternative, thanks to persistent driver developers and usersBUT: more complicated setup and compatibility problems with old hardware

• Main challenge turned out to be the antenna/LNB alignment• Pointing• LNB Skew angle• LNB focussing (sometimes requires new LNBs)

EUMETCast DVB-S Status January – June 2014

The chart here shows the monthly system availability for the three EUMETCast services covering Europe, Africa and South America respectively. Both EUMETCast Africa and EUMETCast South America systems are, in effect, extensions of EUMETCast Europe and thus the end-to-end system availability is calculated taking due account of the availability of EUMETCast Europe and of the respective extensions.

Events which impacted availability:

Feb-April 2014: Antenna – satellite – sun colinearity had some impact on EUMETCast Africa and South America services.

20Slide: 20

Basic Service

• “The Basic Service will provide the same availability as the current DVB-S service, assuming the existing antennas are being used”?

• Despite lower signal values the target link margin can be reached and the yearly availability as well, for most of the existing antennas.

• LNB replacement might be necessary

21Slide: 21

Further DVB-S2 Planning

October• C-band services switch to DVB-S2 feed (October)

(C-band Americas already validated)• Operational service Monitoring based on DVB-S2

(October)• High Volume Service completion of formal tests

(functionally ok)

November/December• Preparations for switch off of DVB-S• Planned “outages” end Nov/early Dec• A termination of the DVB-S Service before holiday

period is being discussed

22Slide: 22

Further DVB-S2 Planning

2015

• Cleanup activities (data duplication, DVB-S system, etc.)

• Start of operational High Volume Service (Sentinel-3)

Further Evolution

• Existing client licenses remain valid with the 2.4 clients;

• New client version (2.12) with fixes (java security, etc.) new functionality and better performance currently prepared for release, and will be available Q1 2015 (including license);

• Future evolution of clients depending on the needs, e.g. 64bit versions, other platforms

• New EKUs (eToken 72K), including more modern Linux drivers
