  • Multi-spot transmission and reception system on board a satellite and satellite comprising such a system
    Patent number: 8542626
    Abstract: A multi-spot transmission and reception system includes at least one outbound section implementing the reception of a hub frequency band and its transposition into user transmission sub-bands, at least one return section implementing the reception of user frequency sub-bands, and their transposition into a hub transmission band and a mesh section comprising a digital transparent processor DTP. The mesh section includes: frequency sampling and recombining means to sample, on user reception sub-bands a mesh band fraction, and to recombine the sampled mesh band fractions on an input of the DTP; and frequency division and reinjection means to divide the frequency band routed to an output of the DTP, into band fractions, and to reinject the band fractions obtained into the user transmission sub-bands. An application of the system is to repeaters on board telecommunications satellites.
