| 1. A system for antenna tracking, comprising:
means for detecting orthogonally polarized signals of a tracking channel, determining which of the orthogonally polarized
signals is stronger, suppressing a cross polarization response of the tracking channel, and increasing the accuracy of tracking
of incident signal direction to minimize antenna pointing loss; and
a controller configured to select a polarization of a data channel depending upon which of the orthogonally polarized signals
is stronger;
wherein the tracking channel and the data channel are two different channels;
wherein the means for detecting orthogonally polarized signals of a tracking channel, determining which of the orthogonally
polarized signals is stronger, and suppressing a cross polarization response of the tracking channel includes
means for combining the orthogonally polarized signals after the orthogonally polarized signals are detected.
