摘要

基于MS—3型磁强计和GPS接收机

实现了真航向角的测量。设计出了基于中值滤波预处理和最佳椭圆假设的磁强计罗差补偿算法

辅助以GPS提供的位置信息得到磁偏角。在此基础上

设计了一组模拟不同类型干扰磁场的磁强计数据采集实验。实验结果表明:补偿后的磁强计航向误差可以减低到0.6°以内。

Abstract

The real roll pitch can be measured with MS-3 magnetometer and GPS receiver.The algorithm of magnetic deviation compensation is presented

which is based on ellipse hypothesis.A set of data collection and magnetic deviation analysis experiments which can simulate different magnetic disturbances are designed.The data is presented by using effective arithmetic based on the help of GPS.The experimental result indicates the error about magnetometers is reduced to less than 0.6° after compensation.
