摘　　要：为了提高激光陀螺捷联惯性导航系统的导航精度,对惯性器件误差进行了原理上的分析和说明,并针对由国内某型激光陀螺构成的惯性测量器件进行了误差分析.在此基础上建立了精确的误差模型,并采用多位置标定法标定出了加速度计的误差系数,采用分立标定法标定出了陀螺的误差系数.An error compensation technology was presented to improve the navigation precision of laser gyro strapdown inertial navigation system, which has an effect on the navigation precision. The system errors mainly result from the inertial instrument errors, which must be eliminated in order to decrease the system errors. This paper emphasized the principle analysis of the inertial instrument errors, built the exact mathematical models and adopt the many positions calibration to calibrate parameters of the error model of the accelerometer and schism calibration to calibrate parameters of the error model of the gyro.
