摘要

摘要: 在理想电磁环境中对姿态测量元件电子罗盘进行了校准，给出了校准所需的标准参数设置。分别对电子罗盘在理想电磁环境与单交变磁场环境中以及二重及三重交变叠加磁场环境下的姿态角输出进行了对比分析，实时测量了两种典型状态下罗盘局部交变干扰磁场强度并绘出二维交变图。结果显示：随着交变干扰磁场强度的增大，3个姿态角输出精度均呈降低趋势。尤其是航向角最为严重，这与其特殊的敏感原理吻合。文末给出了精度变化的电磁数据原因。提出了避免罗盘精度降低的方法。

Abstract: A 3 axes compass module is calibrated in ideal magnetic environment, and standard calibration parameters are put forward. The output of compass module is measured and compared in ideal magnetic environments of single, two and three alternating magnetic fields. Real-time alternating magnetic density about compass module in two representative states was measured and the result was given. The result shows that the precision of compass module decreases with the increase of the magnetic density, especially at heading direction, which agrees with specific sensitivity theory of compass. The reason of this phenomenon is given and the method of improvement is suggested.
