在自动跟踪过程中校正电子罗盘的航向数据

Rectify the heading angle of electronic compass in automatic track progress

介绍了依据地理坐标角和载体坐标角的转换矩阵和当前地理位置对星的理论指向角推算出准确的航向角,修正电子磁罗盘的航向。

The method that figures out current true heading by the matrix for converting geographical angle to carrier's angle and the angles pointing at satalite in current position is introduced,then the heading provided by Electronic Compass is corrected by the result.
