- METHOD AND APPARATUS FOR IMPROVING POSITION-VELOCITY SOLUTION IN GNSS RECEIVERS

摘要

Embodiments include an apparatus and method for improving a Position-Velocity Solution in a Global Navigation Satellite System (GNSS) receiver. The receiver of the mobile terminal includes an antenna for receiving at least one signal from at least one satellite, a measurement layer dependent on the at least one signal to generate distance and rate-of-change measurements, and a hissing device dependent on the distance and rate-of-change measurements. and a storage device for storing toric satellite measurement states. The receiver may further include a Kalman filter logic section for receiving the distance and distance change rate measurement values and smoothing the calculated motion of the mobile terminal. The storage device may store a historical filter state. The filter adjustment logic section detects a measurement layer error trigger, removes or lightweights the error information associated with the measurement layer error trigger, and repeatedly applies the filter logic section to the historical filter state so that the filter logic section is currently filter You can update the status.
