摘要： A device and method for neutralizing the effect of a jamming signal on a satellite. The device is configured to be on the ground and it includes an identification device configured to determine parameters of the jamming signal; a processor configured to generate a replica of the jamming signal; an emitter configured to broadcast the replica of the jamming signal on the uplink of the satellite.

摘要： A data collection device carried on board a satellite and making it possible to localize a source of interference, without using neighboring satellites, comprises: a reception device able to receive the frequency on the ground of the interference; at least three antenna points arranged on the satellite so as to be able to receive a radiofrequency signal coming from the target surface; a processor able to determine the amplitude of the interference signal at the level of each of the antenna points; a connection device able to connect successively each of the antenna points to the processor.

摘要： A method for aligning an earth station antenna with a satellite antenna includes sending an uplink signal from the earth station antenna to the satellite antenna; measuring at least a strength of the uplink signal received by the satellite antenna; sending by telemetry the measured signal strength to a telemetry station; adjusting the orientation of the earth station antenna in order to maximize the measured signal strength.

摘要： A flexible payload for a satellite includes a main uplink antenna device configured to receive at least a main uplink signal over a main coverage area; a reconfigurable uplink antenna device configured to receive a complementary uplink signal over a complementary coverage area; a command device configured to define the complementary coverage area of the reconfigurable uplink antenna device, and an agile converting device configured to generate a spectral hole in the bandwidth of the main uplink signal.
