New method for evaluation of transfer alignment accuracy based on reverse navigation

Abstract

This paper deals with the transfer alignment accuracy evaluation problem of air-to-air missile. The conventional accuracy evaluation methods often use optimal smoothing technique, which need complex computation and abundance data storage. This paper presents an alternative method, which uses Kalman filter to estimate inertial sensors bias and reverse navigation algorithm to compute the reference attitude. The reference attitude is used to evaluation the transfer alignment accuracy. A simulation is conducted. The simulation results verify the feasibility of the proposed method and show that the new method can give an accurate evaluation of transfer alignment accuracy.
