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
