Beidou GPS dual mode uses the "current" statistical model and the Kalman filter. Its system noise and observation noise are unknown and time-varying, and the upper and lower limits of acceleration can not be adapted to the current acceleration of the unknown motion law of the UAV, resulting in the reduction of navigation accuracy. The program is the corresponding MATLAB simulation program.
