For the ship maneuvering performance is poor, and the problem of the drift of the gyro diverges with time, filtering precision of the INS transfer alignment reduction caused by random disturbance such as elastic deformation. An adaptive incremental Kalman filtering algorithm based on the "velocity+position+attitude" matching method is proposed.. In this algorithm, the state space model of transfer alignment is established, designing classified adaptive factors, structuring adaptive incremental Kalman filter. Computer simulation results show that this algorithm can improve the used-ratio of SINS information, realize rapid alignment only under the ship swaying state, realize real-time estimation of time variable noise, alignment precision is high and the prospect of engineering application is broad.
Key words: SINS; transfer alignment; classified factors; adaptive; incremental filter
