Claim of US Patent No. 10,397,920

1. A method of satellite communication, comprising:at a first satellite, providing a feeder beam using a first combination of frequency band and antenna polarization, the feeder beam is associated with a feeder beam coverage area;
transmitting from the first satellite to a second satellite a first set of inter-satellite communication signals based on first data received from the feeder beam;
at the second satellite, providing a service beam using the first combination of frequency band and antenna polarization, the service beam is associated with a service beam coverage area that is at least partially overlapping with the feeder beam coverage area; and
transmitting from the second satellite to the first satellite a second set of inter-satellite communication signals based on second data received from the service beam,
wherein providing the service beam comprises:
receiving a first set of uplink signals using the first combination of frequency band and antenna polarization;
transmitting a first set of downlink signals using a second combination of frequency band and antenna polarization;
receiving a second set of uplink signals using the first combination of frequency band and antenna polarization; and
transmitting a second set of downlink signals using the second combination of frequency band and antenna polarization.
