By building the velocity plus attitude matching mode for ship transfer alignment, we analyze the impact of different hull deformation angles to the performance of transfer alignment and give simulation results. The theoretical accuracy of GPS attitude determination network applied for ship hull deformation monitoring is proposed. According to the simulation results, the performance of transfer alignment after hull deformation compensation by the monitoring network is effectively improved compared to the one without compensation.

The transfer alignment processes of the ship-borne weapon and the shipboard aircraft are limited by ship0s maneuver, for large ship, it is hope that the transfer alignment can be executed just under the circumstances of sea wave without any intentional ship0s 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 ships 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.
