磁快速定向系统自差补偿研究

Study on Deviation Compensation for the Magnetic Quick Orientation System

介绍一种基于巨磁阻传感器的定向系统,该系统结构简单、成本低、精度高。阐述了定向系统工作原理,由于电子定向系统存在着自差,分析了定向系统影响自差的各种因素,利用椭圆假设对磁定向系统的自差进行了有效的补偿。

A newly developed high accuracy and low cost orientation system is introduced in this paper. The constitution and theory of the orientation system are presented. But there is deviation on the orientation system. In order to remove the deviation of the magnetic orientation system, the factors of the deviation are analyzed. The deviation is removed greatly by the ellipse hypothesis. In the end, the application and the prospect of the orientation system are briefly described.
