To solve the problem of transfer alignment on moving base when the ship moving, introduce 2 kinds of transfer alignment for wander azimuth laser inertial system (LSINS). Choose the ship carried LSINS as main INS, and plane carried LSINS as sub-INS. Simulated by kalman filter, also analyze the 2 different methods. The simulation result showed that both methods meet the requirements of transfer alignment accuracy and the practical application of engineering. The methods are useful to engineering application.
