Abstract

Future advanced mobile and personal satellite communications systems, such as the ICO orbit Inmarsat-P system and GEO regional systems, require digital signal processing to provide the necessary flexibility in the routing of channels to/from the multiple beam mobile link coverage. The paper describes a hardware demonstrator, developed under ESA contract, which is capable of demonstrating both switch-based wideband beamforming and digital narrowband beamforming architectures. The central elements of the demonstrator are 4 ASICs, developed in flight representative radiation hard technology, which may be flexibly configured to demonstrate various architectural options.
