The supply side: some of the key evolutions for the future
October 2014
International Conference on Space Optics – ICSO 2014, Tenerife, Canary Islands
5
Enhanced in-orbit flexibility in power, bandwidth and coverage
For best use of the total available satellite capacity
For connectivity between beams
For concentration / densification of capacity in specific hot zones
Increase of demand in the upper range for very high capacity payloads
Enabled by Electric Propulsion to keep launch mass compatible with reference launchers
requested by operators
Further optimisation of the satellite and system resources
Use of higher frequency, photonic technology and optical communication for feeder links in the
longer term
… Translating into change in satellite architectures and end-to-end performance
Uplink Flexible Coverage
Various “satellite product routes” forward in answer to the multi-
dimension evolution of the demand

From market needs to enabling technologies
Fixed HTS Missions • Objective: increase total capacity with
a uniform or non-uniform beam
mapping
– Very high capacity density (e.g :
capacity/km2 > 20 to 50 * Ka-Sat)
– Lower cost per bit
– Fixed resource allocation

Photonics input sections: leading to mass/footprint reduction
• Several conversions in one mixer using
Wavelength Division Multiplexing (WDM)
substantial reduction of required number of
convertors
• Optical routing/switching/filtering of the DoCon
output signal
• Photo-detector to convert the signal back to RF
• LO signals distribution by optical fibre
mass reduction compared to co-axial cable
improved EMC as a by-product.

Conclusions
Significant savings in Payload Architectures offered by use of photonic technology
Mass saving ~ 35% (excluding harness & frequency generation)
Harness mass saving ~ 25% at payload level
Lower number of units – programmatic savings
Advantages in EMI/EMC
Optical interconnections
Still at Low TRL
Industry capability at component level
Need to overcome challenges for high density packaging and integrated chip solutions
Key functions within payload
Input section between LNA & HPA
Frequency generation units
Photonic RF frequency conversion
Photonic switching and routing
