PAYLOAD ARCHITECTURE OF A TELECOMMUNICATIONS SATELLITE

摘要

The present invention relates to a payload (50) of a satellite comprising a gateway reception module (51) and a user transmission module (53), said user transmission module (53) comprising: - an asymmetric switching matrix (54) comprising N input ports and N∙M output ports; - a multi-beam antenna (55) adapted to form N∙M static beams comprising N∙M input ports respectively connected to the N∙M output ports of the asymmetric switching matrix (54); - power amplifiers integrated in the multi-beam antenna (55) or arranged between said multi-beam antenna and the asymmetric switching matrix (54), the payload further comprising a digital processing circuit (52) configured to demultiplex received signals multiplexed by the gateway reception module (51), and to distribute said signals over various input ports of the asymmetric switching matrix (54).
