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

Improved link budgets, and smaller user terminals

Send the data where it is actually required

Small contribution links are possible

Limited jamming impact

Why on-board processing ?

Single hop

Efficient use of resources

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
