针对不同型号的捷联惯性导航系统(SINS,Strapdown Inertial Navigation Sys-tem)测量量程及动态性能差异大,而常规标定方法难以提供多动态性信号激励的问题,提出一种利用离心机和转台对SINS进行整体标定的新方法.通过将转台安装在离心机上,调整转台姿态以及离心机旋转速度和旋转半径,可对SINS提供多范围、多运动形式的信号激励,实现对不同参数特性SINS的标定.建立了完整的离心机转台控制模型并对其进行了仿真验证,利用转台依次调整SINS到6个不同位置,控制离心机对每个位置进行正反两次共计12次旋转,即可标定出整个系统的24个误差参数.理论分析表明:该标定方法简单易操作,数据利用率高,激励信号设置灵活,具有一定的工程应用价值.
The measurement range and dynamic performance of SINS (Strapdown Inertial Navigation Sys-tem) differ greatly for different models. However, the conventional calibration method is difficult to provide multi-dynamic signal excitation. A centrifuge and turntable SINS for a new method of calibration as a whole.The SINS can provide multi-range, multi-motion signal excitation by installing the turntable on the centrifuge, adjusting the turntable attitude and centrifuge rotation speed and rotation radius, so as to realize the calibration of SINS with different parameter characteristics A complete centrifuge turntable control model was established and verified by simulation, using the turntable in order to adjust the SINS to 6 different locations, the control centrifuge for each position a total of 12 times of positive and negative rotation can be calibrated 24 error parameters of the whole system.The theoretical analysis shows that the calibration method is simple and easy to operate, the data utilization rate is high, the excitation signal is set flexible, and has certain engineering application value.
