A satellite 14 receives transmissions and configuration commands from different earth stations 12 via a feeder link, and retransmits each transmission in a configuration determined by the corresponding configuration command. The configuration commands select a beam, power level and frequency for retransmission. The satellite 14 can receive on the feeder link from any one of the earth stations 12 at any one time, by means of a broad beam feeder link antenna covering the whole field of view of the satellite 14 on the earth. <IMAGE> |
