Claim:
1. A method for establishing radio frequency links via a multispot telecommunication satellite having several spots between at least one gateway and a service area comprising a plurality of elementary covering zones, designated cells, each cell being associated to a spot and comprising a plurality of terrestrial terminals, said method comprising establishing a forward link between the gateway towards the plurality of terrestrial terminals that comprises: a first step of uplink emission in which the gateway emits a first analog radio frequency signal towards the multispot satellite, said first analog radio frequency signal being emitted with a first spectral efficiency; a second step in which a payload of the multispot satellite receives the first analog radio frequency signal; a third step in which the payload of the multispot satellite processes the first analog radio frequency signal, said multispot satellite processing comprising: a fourth step of downlink emission in which the payload of the multispot satellite emits said plurality of second analog radio frequency signals towards cells, said plurality of second analog radio frequency signals being emitted with a second spectral efficiency, the first spectral efficiency being greater than the second spectral efficiency.
