利用Kalman滤波技术对捷联惯导在准静基座条件下初始对准的失准角进行估计,进而实现惯导系统的自寻北。提出了对激光陀螺进行速率偏频的办法,解决了寻北的精度问题,并给出了实现导弹水平瞄准的方法。
The Kalman filter technique is used to estimate the misalignment angle of SINS initial alignment in the quasi-static base, and then to realize the self-search of the INS. A method of rate-biasing the laser gyroscope is proposed, which solves the problem of seeking accuracy in North China and gives a method to realize the aim of the missile.
