摘要
针对激光陀螺测角仪在转台不同角位置处的脉冲偏置对测角误差的影响开展研究,将谐波分析法应用于激光陀螺测角仪的偏置标定。首先对激光陀螺测角仪的测角误差源进行分析,阐述了激光陀螺测角仪不同脉冲偏置对测角误差的影响;将多位置偏置标定法和谐波分析法相结合,对激光陀螺测角仪输出的角度值进行误差补偿。搭建激光陀螺测角仪角度测量系统,验证激光陀螺测角仪采用多位置偏置标定法后的测角精度,实验结果证明多位置偏置标定方法可以将激光陀螺测角仪的测角精度由0.75″提高至0.58″。
The effect of pulse bias on the goniometric error of laser gyroscope at different angular positions of the turntable is studied,and the harmonic analysis method is applied to the bias calibration of laser gyroscope.Firstly,the source of goniometric error of laser gyroscope is analyzed and the effect of different pulse bias on goniometric error of laser gyroscope is explained.The multi-position bias calibration method and harmonic analysis method is combined to compensate the angular value of laser gyroscope output.The experimental results prove that the multi-position bias calibration method can improve the goniometric accuracy of laser gyroscope from 0.75″to 0.58″.
