摘　　要：此文给出了磁通门磁罗经主要误差的简化模型分析,并基于这种分析讨论了误差的自动补偿方法。经过试验与仿真分析,系统补偿后的精度有很大的提高,并具有体积小、结构简单、反应快和可靠性高等优点。This paper presents the error model analysis of magnetic heading system consisted of two fluxgate magnetometers and a single-chip microcomputer, and gives the compensation as well. Test and experiment proves that it has higher preision, when compared to gyro compass, is smaller in size, lighter in weight, simpler in contruction and more reliable.
