A navigation and positioning model based on pseudo range measurement error is presented according to the orbit parameters and characteristics of GPS system. GPS solution accuracy is simulated and analyzed by using Extended Kalman Filtering algorithm. The simulation result has shown that Extended Kalman Filtering (EKF) algorithm is capable of providing higher filtering accuracy, better than Least Squares algorithm. Thus, it can all the more satisfy positioning accuracy of GPS users.
