摘要

随着光纤陀螺的逐步发展、成熟

光纤陀螺捷联惯导系统也必将得到广泛的应用。在分析罗经法初始对准原理的基础上

对方位和水平姿态未知条件下的静基座捷联惯导罗经对准方法进行了改进。将经典的四步对准方法:水平对准、方位粗对准、再次水平对准和罗经对准

简化为三步对准方法:水平对准、方位粗对准、罗经对准。并用此方法对光纤陀螺捷联惯导系统静基座初始对准进行了实验

实验结果表明:此方法在保证罗经法初始对准精度的基础上

缩短了对准时间。

Abstract

With the rapid development of fiber-optic gyroscope in china

the strapdown fiber-optic gyro inertial navigation system is widely used.Compass method for initial alignment is studied and the improvement is proposed for SINS on stationary base with unknown azimuth and horizontal attitude.Four-step initial alignment method show in classic has been simplified into three steps which are horizontal alignment

azimuth coarse alignment and compass alignment.The initial alignment test with the new method has demonstrated that the alignment can assure precision and reduce alignment time.
