Abstract

A method for processing the problem resulting from master inertial navigation system (MINS) data delay in transfer alignment was presented. When the slave inertial navigation system (SINS) got the MTNS reference data, the data was processed by Kalman filtering and the time origin was unified to the moment corresponding to the MINS data; the current error estimation of the SINS was obtained by time update. Simulation results show that the transfer alignment performance is im?proved by compensating data delay; in the fast and high accuracy alignment it is necessary to take the MINS reference data delay into account.
