Abstract
Described herein are space based subsystems of a satellite, and related methods, for use in producing an optical feeder downlink beam in dependence on RF service uplink beams received from service terminals within a specified RF frequency range. Beneficially certain embodiments eliminate the need for any type of frequency conversion equipment in the spaced based subsystem that is used to produce the optical feeder downlink beam. Also described herein are ground based subsystems, and related methods, for use in transmitting an optical feeder uplink beam to a satellite configured to receive the optical feeder uplink beam and in dependence thereon produce and transmit a plurality of RF service downlink beams within a specified RF frequency range to service terminals. Also described herein is are space based subsystems of a satellite, and related methods, for use in transmitting a plurality of RF service downlink beams to service terminals.
