In order to increase the positioning accuracy of the vehicle navigation,the nonlinear dynamic filter algorithm is presented based on the Global Positioning System.The method sets up the dynamic positioning model of the vehicle navigation.According to nonlinear equation it can obtain accurate mean and variance of the posterior probability density function,and can correcte the positioning accuracy of the vehicle navigation.Simulation results indicate that this method overcomes the distortion of problems caused by the spread filter of the dynamic GPS positioning information and improves the precision of the filter.
