Patent ID: 8509144

Claim:
A method for communicating using a satellite having a forward link capability comprising: providing the satellite, the satellite comprising a plurality of receivers having inputs and outputs, a plurality of transmitters having inputs and outputs, the inputs of the plurality of transmitters coupled to the outputs of the plurality of receivers, a plurality of transmit switches coupled to the outputs of the plurality of transmitters, and a gateway switch structure coupled to at least one of: (a) the inputs of the plurality of receivers, (b) the outputs of the plurality receivers and the inputs of the plurality of transmitters, or (c) the outputs of the plurality of transmitters; using each transmit switch in the plurality of transmit switches to sequentially switch a forward link signal into multiple fixed location beams according to a beam group transmit switching pattern; prior to a time T 1 , using each of at least P receivers in the plurality of receivers to receive a different one of at least P forward link signals from P gateway terminals, and in the duration of one frame, using the gateway switch structure to sequentially switch the at least P forward link signals from the P gateway terminals, in order to provide the at least P forward link signals to the plurality of transmit switches, according to a first gateway switching pattern, and sequentially switching each of the at least P forward link signals into fixed location beams according to a first beam group transmit switching pattern; after time T 1 and before a time T 2 , using each of at least Q receivers in the plurality of receivers to receive a different one of at least Q forward link signals from Q gateway terminals, and in the duration of one frame, using the gateway switch structure to sequentially switch the at least Q forward link signals from the Q gateway terminals, in order to provide the at least Q forward link signals to the plurality of transmit switches, according to a second gateway switching pattern, and sequentially switching each of the at least Q forward link signals into fixed location beams according to a second beam group transmit switching pattern; wherein P and Q are both non-zero, positive integers, and Q<P; and wherein the first and second gateway switching patterns are different.
