  • The Kalman filtering method with track constraints is presented and Kalman filtering equations are derived. Integer ambiguity resolution with road constraints based on LAMBDA is given. Float ambiguity is obtained by the Kalman filter with road constraints. Vehicle based GPS tests were carried out to show the feasibilities of the proposed method and the results indicate that the proposed method can improve the accuracy of float ambiguity and enhance ambiguity resolution speed and successful rate efficiently.
