发明名称 Polarization Re-alignment for Mobile Satellite Terminals
摘要 A system for allowing ground terminals, specifically mobile ground terminals, to dynamically and electronically realign signal polarizations to match that of incoming and outgoing signal polarizations from designated space assets, specifically communications from satellites, comprising an adaptive re-orientation technique based on a cost minimization function, and a means of direct calculations of weighting components based on the knowledge of the orientation and bearing of both the satellites and the ground terminals. The embodiment will allow a mobile ground terminal to electronically realign itself to the signals of a satellite, without the need for mechanical processes to physically re-orient the antenna array.

主权项 1. A method for measurement realignment, comprising: obtaining a first factor and a second factor;resolving a third factor based on information comprising an offset measurement and said first and second factors;resolving a fourth factor based on information comprising said offset measurement and said first and second factors;calculating a first cost based on information comprising a cross correlation between said third and fourth factors; andafter said calculating said first cost, calculating a cost gradient.
