Piggy-Back Satellite Payload
First Claim
1. A method for utilizing excess satellite bus power comprising:
- receiving a signal in a feeder beam in a forward direction from a gateway to a communications satellite for relay to a user terminal;
consuming an occupied portion of an available amount of bus power of the communications satellite using an existing payload of the communications satellite;
consuming a further portion of the available amount of bus power for an additional payload using a plurality of satellite-based transmission amplifiers performing amplification to generate respective service spot beams;
receiving the signal at the communications satellite and amplifying the signal using one of the plurality of satellite-based transmission amplifiers to produce an amplified signal; and
sending the amplified signal to the user terminal, the amplified signal being sent as a service spot beam.
