摘要
本文介绍了几何式静电陀螺监控器的基本结构、工作原理和导航方程；并着重介绍了静电陀螺监控器的自对准。由于几何式静电陀螺监控器的工作特点，在对准时，只需精确的位置座标而不需要航向信息。根据极轴陀螺的动量矩轴绕地球极轴的圆运动，用卡尔曼滤波技术对陀螺框架上的角度传感器输出进行数据处理，即可估计航向角和极轴陀螺的动量矩轴相对地球地轴的初始偏差角。
this report discribes the peration principle and navigation equations of geometric inertial system as an electrostatically supported gyro monitor system(ESGM),especially its self alignment technique. Dnuring alignment,the external pre- cision position data are only used,but the information of the heading of the vehicle is not needed.Since the movement of the vehicle angular momentum vector of the pole gyro around the pole axis is circular,the heading and the initlal error angles can be estimated using the outputs of the angular sensors in the gyro gimbals by Kalman filter technique.
