orientation star
1.On the basis of initial localization and orientation errors occurred in mobile launching of ballistic missile, and impact errors due to drift of the reference coordinate of the inertia] guidance system, the paper describes three purposes able to be obtained by using the inertial navigation system together with the star trackers.
2.With the measured information of the platform gimbal sensors and the star tracker mounted on the platform base board, strapdown celestial guidance scheme solves for the impact point deviation of the missile due to the initial localization and orientation errors, then,the terminal boost coatrol system performs correction of the trajectory.
