Abstract (2. Language): 
Transfer alignment of strapdown inertial navigation system (SINS) for the ship-borne equipment, always utilize the message from master inertial navigation system on the ship. Rapid transfer alignment methods such as “velocity plus attitude” and “velocity plus rate” has been developed by researchers in this area, for the improvement of the rapidness of the transfer alignment, but the accuracy is poor when the flexure of the ship is grievous under abominable environment, the previous research shows that the flexure along different axis of the ship is always not the same, aiming at this problem, theoretical analysis of the effect about the flexure along every axis on the transfer alignment accuracy has been done, find out that the rate of the ship, which is disturbed by flexure rate seriously, depressed the transfer alignment accuracy much more than the other two axis, based on the theoretical analysis, a new rapid transfer alignment prototype named “velocity plus partial rate” matching is presented, by subtracting that rate of the ship from the conventional rate measurement message. Sufficiently utilizing the sway maneuver and avoiding the influence of the flexure, can obtain higher precision and less computational cost than the “velocity plus rate” matching rapid transfer alignment, while the flexure of a certain axis is severity. Simulation system is developed for the evaluation of the presented algorithm, results show that the presented method can obtain higher accuracy than the “velocity plus rate” matching rapid transfer alignment under worse environment, and evidently reduce the computational cost while applying Kalman filter for the estimation task.
