Abstract
A systematic pointing error model is used to calibrate antennas in the Deep Space Network. This article describes and analyzes the least-squares problem and the solution methods used to determine the model’s parameters. Specifically studied are the rank-degeneracy problems resulting from beam-pointing error measurement sets that incorporate inadequate sky coverage. A least-squares parameter subset selection method is described and its applicability to the systematic error modeling process is demonstrated on a Voyager 2 measurement distribution.
