Research on the Method of Acquiring High Dynamic GPS Signal Based on the Union of AF and UKF Technology

摘要：

The problems of receiving GPS signal in high dynamic circumstance are analyzed in this paper, and a method of acquiring high dynamic GPS signal based on the union of Ambiguity Function (AF) and Unscented Kalman Filtering (UKF) technology is studied too. Through this method the pseudo-code time delay and the Doppler frequency of GPS signal could be estimated at the same time. Compared with the MLE, this paper analyzes the acquiring performance of this union estimating method. And simulation results show that its acquisition speed of GPS signal is increased on a certain tracking accuracy.
