The Weight of Telecom in Space
ESA Telecommunications
Our mission is to keep European companies competitive in the area of satellite communications
We do this through:
Coordinating European with national space telecommunications programs
Funding many projects that demonstrate new innovative technologyon ground or on space, or new applications that use satcom
Close to market projects we fund 50%
Early research, prototyping, proof-of-concept we fund 100%
Supporting standardization efforts
ESA ARTES programs
ARTES = Advanced Research in Telecommunications Systems
ARTES has different elements
ARTES 1 = Strategy
ARTES 3 = Multimedia
ARTES 4 = Partnership
ARTES 5 = Technology
ARTES 8 = Large Platform
ARTES 11 = Small satellites

Why on-board processing ?
No second satellite hop, improves user perception forinteractive applications (WWW, VoIP)
Improved link budgets, and smaller user terminals
Send the data where it is actually required
Small contribution links are possible
Limited jamming impact

NEW: Small GEO satellites
Why ?
Currently, almost a monopoly in this market (U.S.)
For new operators/ new entrants
Could cover only a small geographical area
Could be used to “try” the market
Might be used for niche services
Driven by Industry requests
Large and small platforms –example of possibilities
Current satellite has 54 transponders = 350 television programs
In future new standards will be used for satellite television reception DVB-S2 and HDTV, with improved data compression standards MPEG-4/AVC/WM9 (> 2008)
On a small GEO satellite this would allow you 150 HDTV programs
An Alphasat satellite would provide you with 910 HDTV programs
Standardisation
Current DVB-RCS standard for satellite communicationsupported by ESA
DVB-RCS terminals start to be interoperable: no sole sourceanymore
A separate body has been created (independent from ESA)
SatLabs compliance test program initiated by ESA: first fiveterminals manufacturers are now officially compliant
Harmonisation in the area of meshed connectivity, QoS, management, DVB-S2, higher layer protocols (TCP and HTTP acceleration) started
Standardisation (2)
Current DVB-RCS standard evolving for:–communications on the move, –Harmonised management and QoS–meshed connectivity
DVB-S2/RCS also of interest of DISA:–Recommendation for DVB-S2, RCS (star & mesh) alongwith encryption of signaling
–Plans to use RCS for two-way GBS
–Part of Joint Net Centric IP Modemdevelopment
