摘要

Telemetry data communication relay platform from one or more satellite (s) moving down to the ground A communications relay platform of a space observation system, on board an aircraft ( 34) overlying the clouds, includes a first receive interface (104) for demodulating telemetry data of at least one observing traveling satellite (4, 6), a second transmitting interface (108) for modulating and transmitting the received data to at least one destination ground station (12, 14, 16). The relay platform comprises a first downlink dual decryption / encryption chain (204) of telemetry data repatriated from at least one traveling observation satellite (4, 6) to the destination ground station (s) (4). 12, 14, 16).
