| 摘 要： | 介绍了单轴旋转调制水平基准消除机抖激光陀螺漂移和加速度计偏置的原理，并对IMU安装误差原理做了理论分析，利用矩阵旋转变换法推导出安装误差角的计算公式。用得到的安装误差角进行标校大大降低了水平基准的姿态误差，并在工程中得到了良好的应用。

| Abstract: | The principle which eliminates the dither laser gyro drift and accelerometer bias by using the single-axial rotation inertial level benchmark is introduced. The IMU fixing error is analyzed. The calculated formula of the fixing error angle is derived by rotating matrix transform methods. The attitude error of the level benchmark is reduced by using fixing error angle. |
