Abstract
This disclosure provides systems, methods and apparatus for determining beamforming coefficients that correct for pointing errors. In one aspect, a subsystem of a ground station can receive calibration signals from a satellite. The properties of the calibration signals can be measured and used to determine the pointing error of the satellite. Beamforming coefficients based on the pointing error can be provided by the ground station to the satellite.
