Abstract
Beamforming in a satellite communications network includes determining a first delay imparted to signals redirected by a first reflecting dish in a satellite, the first delay being caused by motion of the first reflecting dish relative to the satellite. A second delay imparted to signals redirected by a second reflecting dish in the satellite is determined, the second delay being caused by motion of the second reflecting dish relative to the satellite. Calculating, using the determined first and second delays, beamforming coefficients that enable the generation of a single beam by combining a group of signals that includes a first signal redirected by the first reflecting dish and a second signal redirected by the second reflecting dish.
