A system includes antennas to receive satellite signals, modems for managing data received from the antennas, and a switching unit for managing the allocation and the transmission of the data from the various antennas to the various modems, the data from any one of the antennas being able to be allocated and transmitted to any one of the modems, the system thus being able to adapt the allocation of the data such that each modem is able to continue to receive data relating to signals transmitted by one and the same satellite upon a change of position of the antennas, thereby making it possible to maintain communication to one or more given satellite communication services.
