Abstract
A system described herein includes a ground based gateway subsystem configured to transmit an RF feeder uplink beam to a satellite, and a space based subsystem of the satellite configured to receive the RF feeder uplink beam and produce in dependence thereon an optical ISL beam that is transmitted to another satellite. The ground based gateway subsystem can include a ground based beamformer used to produce the RF feeder uplink beam. The optical ISL beam, produced by the space based subsystem and transmitted to the other satellite, can comprise a wavelength division multiplexed optical signal having RF frequencies within a same specified RF frequency range within which the other satellite is configured to transmit a plurality of RF service downlink beams, thereby eliminating any need for the other satellite to perform any frequency conversions when producing the plurality of RF service downlink beams in dependence on the optical ISL beam.
