Claim 7:
8. The system of claim 7, wherein the on-board multi-spot communication payload is configured to, in a second phase after the telecommunications satellite has been launched and the N satellite access stations have been brought into service:
in a second step, select a first transmission source of the N transmission sources, wherein the first transmission source corresponds to the first neighboring transmission spot, connect the single output terminal of the at least one opposition matrix to the selected first transmission source, and disconnect the remaining N transmission sources by suitably configuring the switches of the output selection ring;
in a third step, connect a first reception source of N reception sources to the direct input row of the at least one opposition matrix and disconnect the N-1 remaining reception sources from the derived opposition input rows of the at least one opposition matrix, wherein the first reception source corresponds to a first neighboring reception spot of N neighboring reception spots,
wherein the first satellite access station is configured to, in a fourth step, receive a first multiplex of test signals and digitizing, by the first satellite access station, the first multiplex of test signals into a useful acquisition signal, wherein the first multiplex of test signals are transmitted by at least a portion of the N satellite access stations, received by the first reception source, and retransmitted by the first transmission source;
wherein the on-board multi-spot communication payload is configured to in a fifth step, connect one of the N-1 remaining reception sources to a corresponding one of the derived opposition rows of the at least one opposition matrix and disconnect the other N-1 remaining reception sources from the derived opposition rows of the at least one opposition matrix wherein the one of the N-1 remaining reception sources corresponds to the, reception spot covering a third satellite access station of the N satellite access stations;
wherein the first satellite access station is configured to:
in the same fifth step, receive a second multiplex of test signals and digitize the second multiplex of test signals into an interference acquisition signal, wherein the second multiplex of test signals is transmitted by at least a portion of the N satellite access stations, received by the N-1 remaining reception sources and retransmitted by the first transmission source; and
in a sixth step, cause the communication spectrum monitoring device to calculate, calculate a first complex correlation coefficient between the useful acquisition signal and the interference acquisition signal and to determine, based at least on the first complex coefficient, an attenuation value and a phase change value associated with the derived opposition rows, the attenuation value and the phase change value configured to cause rejection of the interference signal generated by the remaining reception source connected to the corresponding one of the derived opposition rows of the at least one opposition matrix on a repeater reception access assigned to a second satellite access station of the N satellite access stations; and

wherein the on-board multi-spot communication payload is configured to in a seventh step, set the remotely controllable attenuators or phase shifters of the at least one opposition matrix by remote control to the attenuation value and the phase change value.
