在分析了影响磁罗盘工作过程中可能存在的误差及其来源，针对罗差误差，提出一种椭圆假设补偿法与最小二乘法求补偿系数相结合的方法对电子罗盘进行标定。实验验证了最大误差达34.2o的电子罗盘系统经过标定补偿后误差降至3o以内，能基本满足一般导航系统的要求。该方法也适用于其他磁罗盘的标定。

The possible error and its source of magnetic compass are analyzed. In view of the compass error,elliptic assume compensation method combined with least square method for compensating coefficient method were proposed here to calibrate the electronic compass. The experiment verified the maximum error is drop from 34. 2o to 3o when the compass system is compensated. And the experiment results demonstrate that the compass system can be used in common navigation field. This method is also applicable to other magnetic compass calibration.
