Abstract
A system for allowing ground terminals, mobile or stationary, to dynamically and electronically re-align signal polarizations to match that of incoming signal polarizations from transmitting sources. An adaptive re-orientation technique utilizes a cost minimization function to determine the difference between actual orientation values and desired orientation values. Calculations of satellite and ground terminal orientations and bearings to create weighting components allow a mobile ground terminal to electronically realign itself to the signals of a transmitting source, thereby eliminating the need for physically re-orienting the antenna array through mechanical processes.
