Abstract:  In order to study the way how the sea conditions and the carrier mobility affect on carrier-based aircraft SINS′rapid transfer alignment, using the attitude error angle as research object,a specific force equation and attitude differential equation of inertial navigation system are established. The error model of velocity matching and velocity plus attitude matching are deduced detailly based on error propagation mechanism. Then simulating and analyzing are carried out with Kalman filter algorithm. The simulation results show, a certain swing amplitude is more conducive to aircraft’s velocity matching or velocity plus attitude matching. Under typical sea conditions, the velocity matching transfer alignment is affected more obviously by aircraft carrier’s line motion.
