The PSDE/SAT-2 multimission satellite designed to offer a flight opportunity to different experimental communication payloads and verify the feasibility of advanced space technologies is described. It was conceived for experiment in the framework of the European DRS (Data Relay Satellite) program thus providing intersatellite and interorbit communication links, but also experimental and preoperative services. Payloads include optical communication single access payload (LSA); S-Band single access payload; S-Band multiple access payload; land mobile experimental payload; navigation payload; 40/50 GHz communication payload; and millimeter wave propagation payload. The orbital slot and interference analysis identified a limited number of orbital positions for the mission interleaved between Eutelsat satellites (i.e., 14 deg 30 min E and 17 deg 30 min E). A coordination is required in Ku-Band with Eutelsat satellites and in Ka-Band with ITALSAT (Italy) and TOR-12 (USSR) systems. The link budget analysis shows that the feeder link can be correctly dimensioned assuming the ground segment as specified by ESA and the feeder link payload interface compatible with the presently available hardware technology. A feeder link interface payload was designed, matching the overall system specifications. The TT and C system architecture is shown to be adequate.
