Abstract
In order to solve the problem of time synchronization between the master inertial navigation system ( MINS) and the slave inertial navigation system (SINS) in the guided rocket' s transfer alignment (TA), firstly the influence on TA of MINS reference information time delay is analyzed in theory, and a method for solving the problem is presented. When the SINS gets the reference information of MINS, the information is processed by Kalman filter, then the current error estimation of the SINS is obtained by timely update. Simulation results show that the method can solve the problem effectively, and realizing the synchronization algorithm is quite easy.关键词
