The document provides an overview of the Eumetcast system's transition to DVB-S2, detailing the implementation and testing phases, including system integration, performance testing, and user feedback. It highlights key improvements in service availability and link margin, as well as ongoing challenges with receiver compatibility and antenna alignment. Future plans include the completion of high volume services and preparations for the switch-off of the older DVB-S service by early 2015.

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

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

Slide: 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)

18. 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

21. Further DVB-S2 Planning
Slide: 21
21
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

22. Further DVB-S2 Planning
Slide: 22
22
2015
• Cleanup activities (data duplication, DVB-S system, etc.)
• Start of operational High Volume Service (Sentinel-3)
