Title: RELAY PLATFORM FOR COMMUNICATING TELEMETRY DATA FROM ONE OR MORE MOVING OBSERVATION SATELLITE(S) TO THE GROUND
Abstract:
Relay platform for communicating telemetry data from one or more moving observation satellite(s) to the ground. A relay platform for communicating from a space observation system, installed on board an aircraft (34) moving above the clouds, comprises a first reception interface (104) for demodulating telemetry data from at least one moving observation satellite (4, 6), a second transmission interface (108) for modulating and transmitting the data received to at least one destination ground station (12, 14, 16). The relay platform comprises a first descending two-level decryption/encryption chain (204) for the telemetry data returned from at least one moving observation satellite(s) (4, 6) to the destination ground station(s) (12, 14, 16).
