Study on a method of rapid transfer alignment

For the rapidity and accuracy which airborne INS transfer alignment requires, the paper analyzed different transfer alignment matching method, chose velocity plus attitude matching method, deduced system error model and measurement equation in detail. Finally, the paper designed a new Kalman filter for simulation with a classic trajectory. Simulation shows that, the estimation of the misalignment angles can reach the accuracy requirement in a short time, the design of simulation is accurate, and the velocity plus attitude matching method is efficient.
