Abstract
A satellite is configured to communicate with a ground base station to provide coverage for communication in a first geographic region, and suppress from the communication, interference from a second geographic region. The satellite includes an onboard beamformer (OBBF), feed array and feeder-link antenna. The OBBF is configured to produce first and second spot beams for respective ones of the first and second geographic regions. The feed array is configured to receive first and second signals in respective ones of the first and second spot beams for respective geographic regions. At least portions of the first and second signals carry respective ones of the communication and the interference. The feeder-link antenna, then, is configured to transmit the first signals and second signals to the ground base station that is configured to suppress any of the interference from at least the portion of the first signals carrying the communication.
