Abstract：In order to assess the system performance, the GPS constellation and the moving trajectory of receiver are simulated, a 11dimensional state PositionVelocityAcceleration (PVA) navigation model is used for analysis. The EKF and EKPF model are separately adopted to obtain the navigation solution, the simulated results show that both the two models are satisfactory, while the navigation performance of the proposed EKPF algorithm is superior to EKF, especially in vertical direction, and impact of multipath effect has been reduced.
