A Scene Matching Backtracking Location Method Based on Convergence Criterion

In this paper, the engineering problems in scene matching positioning system are studied, according to the scene matching positioning of satellite under the condition of denial, establish a volume of physical model, kalman filtering method of indirect filtering residual envelope method is adopted to improve the mismatching points out and jumping back and forth, filtering results using backtracking method to solve the problem of less The precise positioning of the aircraft's own position under the condition of satellite rejection is realized, so as to achieve accurate guidance and strike to the target. The simulation results show that the method described in this paper is effective and has good academic and engineering significance.
