Abstract:
1. A forward link payload for a multi-beam satellite, a forward link allowing receipt of radiofrequency signals from at least one main terrestrial station so as to re-transmit said signals to at least one terrestrial terminal, said payload comprising: one or more reception antennas configured to receive polarised radiofrequency signals; a regeneration device configured to regenerate radiofrequency signals by filtering, frequency transposition and amplification; and transmission antennas configured to transmit the regenerated radiofrequency signals to one or more terrestrial terminals, each signal being destined for a cell corresponding to a single basic coverage area wherein the regeneration device comprises a plurality of regeneration chains, each chain comprising an amplification device configured to amplify two radiofrequency signals having different frequency bands, and wherein the transmission antennas associated with a regeneration chain are configured to transmit two regenerated radiofrequency signals having orthogonal directions of polarisation and destined for cells belonging to a single cell planning which uses at least two frequency bands and two different polarisations and wherein the transmission antennas associated with a regeneration chain are configured to transmit two regenerated radiofrequency signals by said regeneration chain to two non-contiguous cells.
