Abstract
A method for establishing radiofrequency links via a satellite having several spots between a gateway and a service area comprising a plurality of elementary covering zones, designated cells, each cell being associated to a spot and including a plurality of terrestrial terminals, a forward link between the gateway towards the plurality of terrestrial terminals including a first step in which the gateway emits a first analog radiofrequency signal towards the satellite, with a first spectral efficiency; a second step in which a payload of the satellite receives the first analog radiofrequency signal; a third step in which the payload processes the first analog radiofrequency signal, and a fourth step in which the payload emits a plurality of second analog radiofrequency signals towards the cells with a second spectral efficiency, the first spectral efficiency being greater than the second spectral efficiency.
