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
DVB-S2 Implementation, testing 
Slide: 4

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

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

• 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

• 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 
Slide: 13 
13 
• 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
User Experience 
Slide: 14 
14 
• 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 users 
BUT: 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 
EUMETCast  System Availability for the Year-To-Date 
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- 
18 
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.

• “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

EUMETCast system & DVB-S2 migration - EUMETCast User Forum 2014

  • 1. Current EUMETCast System and ongoing DVB-S2 Parallel Operations
  • 3. DVB-S2 Implementation, testing Slide: 3 3 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
  • 4. DVB-S2 Implementation, testing Slide: 4 4 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
  • 5. DVB-S2 Implementation, testing Slide: 5 5 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
  • 6. Service V&V and Pilot Users, results Slide: 6 6 • 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
  • 7. Service V&V and Pilot Users, results Slide: 7 7 3 2 1 0 -1 -2 -3 Pilot sites: difference between measured and expected link 0 0.5 1 1.5 2 2.5 3 difference in link margin (dB) antenna size (m) margin
  • 8. Service V&V and Pilot Users, results Slide: 8 8 • 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
  • 9. Slide: 9 9 New EUMETCast Europe Transponder • Final parameters; Ku-band Transponder EUTELSAT 10A (10° E), Europe Parameter Value Name Transponder EUTELSAT 10A C4 Down Link Frequency 11263 MHz Symbol Rate 33000 kS/s Polarisation Horizontal Roll-Off 5% Transmission Standard DVB-S2 MODCOD 1 — Basic Service 8PSK3/5 MPE transport stream (TS) ISI=1 max 55 Mbps info bit rate (at TS level) max 50 Mbps IP data rate MODCOD 2 — High Volume Service 16APSK2/3 MPE transport stream (TS) ISI=1 max 85 Mbps info bit rate (at TS level) max 77 Mbps IP data rate

  • 13. DVB-S2 documentation Slide: 13 13 • 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
  • 14. User Experience Slide: 14 14 • 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 users BUT: 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)
  • 15. User Experience – LNB Skew Slide: 15 15
  • 16. User Experience – LNB focussing Slide: 16 16
