Pseudorange Smoothing Technology Based on Filtering

Bing Hou, Xiaolin Zhang, Yan Tang

Abstract:	Pseudorange measurement has an important effect on the satellite navigation positioning accuracy. In the high precision positioning, the traditional carrier phase smoothed pseudorange algorithm limits the positioning accuracy. Adaptive Kalman filtering algorithm and a-ß-? filtering algorithm were used to smooth the pseudorange for the purpose of improvement of pseudorange measurement accuracy. Based on theoretical analysis, the simulation results of the two algorithms in static and dynamic scenes show that a-ß-? filtering algorithm is more effective than adaptive Kalman filtering algorithm in low dynamic condition.
