Patent ID: 8542626

Claim:
A multi-spot transmission and reception system on board a satellite, comprising: at least one outbound section comprising a hub reception channel intended to receive first signals originating from an earth station and at least two user transmission channels to transmit the first signals to geographical coverage zones corresponding to users, referred to as user spots, at least one return section comprising at least two user reception channels intended to receive second signals originating from user spots and a hub transmission channel intended to transmit the second signals to the earth station, and an additional link section, being a mesh section, to provide inter-spot links, the mesh section comprising a digital transparent processor (DTP) to filter and route signals from a first user spot to a second user spot, wherein the mesh section further comprises: means for frequency sampling and recombining, comprising at least two inputs connected to a return section, and an output connected to an input of the DTP, to sample, respectively, on the at least two user reception channels, two first frequency band fractions, being mesh band fractions, and to recombine the first two sampled mesh band fractions into a single frequency band applied to an input of the DTP, frequency division and reinjection means comprising an input connected to an output of the DTP, and at least two outputs connected to an outgoing section, to divide the frequency band routed to the same output of the DTP into at least two second mesh band fractions, and to reinject, respectively on the at least two user transmission channels, the second mesh band fractions obtained following division.
