ABSTRACT:
Consistent with one embodiment of the invention, a GPS signal processing system uses a behavior observer to monitor user dynamics and to aid a time-varying-gain filter arranged to perform continuous position and speed estimates. The behavior observer consists of a fast observer and a signal detector. The fast observer tacks user maneuvers. The signal detector compares outputs of the fast observer and the time-varying-gain filter to determine user dynamics and corrects operations of the time-varying-gain filter. Tracking ability is improved without degradation in steady-state position accuracy.
