Abstract:                   

Eutelsat interest in COTS digital components mainly resides in the possibility to drastically increase processing capabilities while maintain SWaP performance at an affordable level for a commercial GEO Satellite mission.

Whatever the communication mission, whatever the frequency band and associated coverages, the digital processing will bring important benefits in terms of being able to flexibly allocate the spacecraft resource to respond to evolutions of the market needs.

Additionally, more generic payload “building blocks” will permit to lower the procurement time while permitting to decrease industrial cost associated to manufacturing, test, integration on satellite, ranging from one-time programming on ground to full SDR (Software Defined Radio) architectures with full on-board reprogramming!
