The scheme USES geomagnetic declination and geomagnetic inclination as matching parameters to acquire rough position.
该方法以磁偏角和磁倾角作为匹配参数进行图匹配，获取粗位置信息。
We also show how to get a local orientation and an approximate formula for geomagnetic declination. Our work clarifies the misconception about polarized wave of antenna.
