摘要

针对地磁导航系统在实际应用中由于电子罗盘安装误差而影响导航系统测量精度的问题,提出了一种有效的标定补偿安装误差角的方法.在分析电子罗盘安装误差角产生机理的基础上,建立了安装误差模型,推导了安装误差角的补偿公式,提出了安装误差角标定方案.通过计算机仿真验证了安装误差角求解算法的正确性.在不同倾角平面上进行了安装误差角标定试验,提出实际操作中对标定平面的要求并验证了补偿结果.%In view of the problem that installation error angle was one of the main reasons seriously affect the accuracy of electronic compass output in geomagnetic navigation to explore effective installation angle error compensation method.Based on the mechanism in the analysis of electronic compass installation error angle,established installation error model,derived compensation formulas for installation error angle and proposed the installation error angle calibration program.Verify correction of the calibration and compensation method by computer simulation.Carried calibration experimentation of installation error angle on different inclination plane,proposed compensation calibration plane requirements and verified the results of actual compensation.
