| 摘 要： | 为校准激光陀螺捷联惯组标定系数误差,介绍了基于捷联惯组开环姿态和速度更新的解析算法.捷联开环更新的姿态误差和速度误差中包含一定的标定系数误差信息,通过转动试验和静止试验可以对标定结果进行评估.通过对开环导航系统误差方程的分析,可以得到刻度系数误差、安装误差的解析解.利用误差解析解可以实现对标定系数误差的校准.在双轴位置...

| Abstract: | To correct for the residual sensor errors of the laser gyro strapdown inertial measurement unit(LSIMU),the analytical algorithm based on attitude and velocity open-loop updating of the LSIMU is provided.The navigation parameter output errors of the strapdown inertial navigation system(SINS) contain certain residual sensor errors that can be evaluated by rotating and static navigation test.The analytical solution of the scale coefficients error and installation error can be deduced from the analysis of the o... |
