为了提高激光陀螺捷联惯性导航系统的导航精度，对激光陀螺的原理进行了分析和说明，重点对影响陀螺比例因子误差因素进行分析，在此基础上建立了误差补偿的精确数学模型，并针对某型激光陀螺进行了误差分析。分析结果表明，惯导系统激光陀螺的比例因子与材料介质、温度、腔长等相关，除了采用稳频技术，还需要采用旋转调制技术提高测量数据精度。转台仿真和实际测试结果证明，该比例因子修正的方法方便、可靠，姿态精度可提高约8.7"，对提高惯导测量精度具有重要意义。

To improve the navigation precision of laser gyro strapdown inertial navigation system ( SINS ) , this paper emphasizes the factor analysis of laser gyro scale factor,and builds the exact mathematical mod-els. Scale factor of a laser gyro is correlated with its material,temperature and field length. Analysis shows that the performance of frequency stabilization and reciprocator rotation is optimal. Table simulations and sailing experiments show that this technology is convenient,and the attitude precison can be improved by a-bout 8. 7". It is meaningful for improving the measurement precison of SINS.
