摘要

弹载捷联惯导系统空中传递对准是机载战术导弹发射前必须完成的任务,其对准精度直接影响导弹系统的制导精度。但传递对准误差无法直接测量,使其评估成为一个难题。文中提出以载机主惯导为参考系统,以主子惯导系统的速度差和位置差作为观测量,采用固定点平滑和固定区间平滑滤波的评估方案。利用Matlab/Simulink建立评估仿真平台,得出仿真结果。分析结果表明,该方案是可行的。

Abstract

It is a puzzled issue for the errors of SINS not directly being measured during in-flight alignment. The scheme proposed in the paper is based on airborne master inertial navigation system (INS), velocity error and location error between the master INS and the slaver INS as exterior values of observation with fixed-point smoothing and fixed interval smoothing filter. The simulation platform was designed by using Matlab/Simulink and the simulation results were given. The analysis results show that the scheme is feasible and valid.

Key words： missile-borne strapdown inertial navigation system; transfer alignment; fixed-point smoothing; fixed-interval smoothing
