Satellite beamforming
First Claim
1. An apparatus comprising:
- one or more processors; and
a storage medium storing instructions that, when executed by the one or more processors, are configured to cause the one or more processors to perform operations comprising;
receiving a first group of signals for transmission through a plurality of amplifiers included in a beamforming satellite;
determining first target terrestrial regions for transmitting the first group of signals;
identifying, in a plurality of feeds included in the beamforming satellite, a first set of feeds for forming beams covering the first target terrestrial regions; and
controlling a switching circuitry included in the beamforming satellite to route the first group of signals from the plurality of amplifiers to the first set of feeds, wherein the first group of signals trigger the first set of feeds to form beams that cover the first target terrestrial regions.

Abstract
A beam former processor receives a group of signals for transmission through the plurality of amplifiers, wherein the group of signals is less than a total number of feeds in an antenna array. The beam former processor determines terrestrial regions for transmitting the group of signals. The beam former processor identifies a subset of feeds that are configured to form beams covering the terrestrial regions. The beam former processor controls the switching circuitry to route the group of signals from the plurality of amplifiers to the subset of feeds through the switching circuitry, such that the subset of feeds are enabled to form beams that cover the terrestrial regions based on the group of signals.
