Abstract

In view of the current problem that long alignment time and low alignment accuracy in traditional alignment methods, a new two-step alignment method is proposed in this paper. This method consists of the coarse and accurate alignment. The feature of gravity vector is used to carry out the analytic coarse alignment. And by applying torque to the platform, the accurate alignment is carried out with extended Kalman filter (EKF). Simulation results show that the estimation error of the azimuthal misalignment angle can converge to less than in eight minutes.
