机抖激光陀螺捷联惯性测量组合的标定方法研究

Study on Calibration Method for Laser Gyroscope Strap-down Inertial Measurement Units

为了提高激光陀螺捷联惯性导航系统的导航准确度,对机抖激光陀螺的抖动偏频产生的惯性仪表输出误差的特点进行了分析,并在标定过程中有效地进行了补偿,提高了陀螺和加速度计的标定准确度。

To improve the navigation accuracy of laser gyro strap-down inertial navigation system, the characteristic of the output error in the accelerometer and gyro by the mechanical dithering of laser gyro is analyzed. Removing the dither-error is necessary to improve the calibration accuracy.
