N2 - The misalignment angle and the lever-arm are affected by the flexural deformation of ship deck, which degrades the transfer alignment accuracy. It is necessary to model and estimate the flexural deformation angle of ship deck, caused by the dynamic lever-arm. By compensating the error to improve the alignment accuracy is extremely vital significance. In this paper, firstly the model between distortion angle and dynamic lever-arm is built and the dynamic lever-arm listed in the state vector is proposed. Finally acceleration matching measurement equation is established and Kalman filtering is adopted to estimate dynamic lever-arm, mounted misalignment angle and distortion angle. The simulation results show that, using the proposed model can estimate dynamic lever-arm, mounted misalignment angle and distortion angle within 10s, which meet the requirements of the alignment precision and time.
