Wireless receiver with tracking using location, heading, and motion sensors and adaptive power detection
First Claim
1. A method for use in a wireless receiver, said method comprising:
- acquiring, by a digital core, a general position input from location, heading and motion (LOHMO) sensors during a coarse acquisition state;
acquiring, by said digital core, a precise position input from power detectors during a fine acquisition state;
entering, by said wireless receiver, said coarse acquisition state when said digital core determines that a power received from said antenna panel falls below a threshold power.

Abstract
A wireless receiver includes an antenna panel providing input to an H-combined/V-combined generation block, a hybrid tracking system receiving input from the H-combined/V-combined generation block, the hybrid tracking system comprising location, heading and motion (LOHMO) sensors for providing a general position input to a digital core, the hybrid tracking system further comprising first and second power detectors for measuring power received from the antenna panel and for providing a precise position input to the digital core, the hybrid tracking system providing phase feedback signals to the H-combined/V-combined generation block. At least one of the phase feedback signals is provided to at least one phase shifter in the H-combined/V-combined generation block to cause a phase shift in at least one linearly polarized signal received from at least one antenna in the antenna panel.
