主要研究了如何利用GPS检定场测量方位角的来校准电子罗盘。将WGS84空间直角坐标转换成站心坐标的模型,利用模型计算检定场两点的方位角。介绍了GPS电子罗盘校准方法,并进行了不确定度分析,最后给出算例验证方法的正确性。

This paper studied how to use the GPS verification field's azimuth to calibrate the GPS electronic compass. The paper introduced the model of conversion the WGS84 coordinates into the topocentric coordinate. And then, the paper used the model to calculate the azimuth between two points of the verification field, introduced the GPS electronic compass calibration methods and carried out uncertainty analysis. Finally, an example was given to verify the correctness of the method considered.
