N2 - The transfer alignment processes of the ship-borne weapon and the shipboard aircraft are limited by ship's maneuver, for large ship, it is hope that the transfer alignment can be executed just under the circumstances of sea wave without any intentional ship's maneuver. Attitude plus angular rate matching and velocity plus attitude matching as the two possible methods which can give accurate estimations of misalignments between MINS and SINS just under swaying maneuver are studied in this paper. Simulation results show that under the circumstance of sea waves and parameters of ship's dynamic deformation, attitude plus angular rate matching filter can give better estimations of misalignment angles than velocity plus attitude matching filter. In addition, the estimation accuracy of attitude plus angular rate matching filter is barely affected by sea condition.
