Research on Integrated navigation algorithm based on hybrid kalman filter

to establish the mathematical model precision bombs MINS/GPS integrated navigation.Aiming at the existing problem of extended kalman filter, the nonlinear filtering, this paper proposes a new filtering algorithm -- mixed kalman particle filter, and applied to the integrated navigation system positioning.The simulation results show that the hybrid kalman particle filter can effectively improve the accuracy and reliability of integrated navigation system.
