Abstract：The traditional navigation mainly based on GPS which provides 3-d position for vehicles has tremendous difficulty in satisfying the stricter requirements for navigation performance in the complex environment of cities. To solve the problem of the navigation accuracy and the reliability of current vehicle navigation,The integrated navigation which combines GPS and DR has been applied to improve the accuracy and continuity of the navigation system. The post-processing method is particle filter. The re-sults show that GPS/DR integrated navigation system can achieve scheduled accuracy. When the GPS signal is broke off,navigation is still effected. However,with the extension of the interrupted time of the GPS signal,the error will also increase.
