Particle Filtering and Its Application for Kinematic GPS Positioning with High Speed Movement

TIAN Shi-jun1,Chen Jun2,PI Yi-ming1(1.School of Electronic Engineering,University of Electronic Science and Technology of China,Chengdu 610054,China;2.Network Engineering Department,Chengdu University of Information Technology,Chengdu 610031,China)  
According to the characteristic of kinematic GPS positioning,a filtering algorithm of kinematic GPS positioning system based on particle filtering is introduced.By means of velocity vector model of mobile station,the system state equations are presented.The standard Kalman filtering algorithm is presented at first,and the application of the particle filtering algorithm in the kinematic GPS positioning system for a moving vehicle with high speed is primarily discussed,and the algorithm is deduced in detail.At last,a simulated example is given.The simulation results indicate that the particle filtering is better than the standard Kalman filtering while GPS receiver with high speed movement or GPS signal is interfered.
