摘要
针对一种新的导航系统—地磁匹配导航的精度进行了研究。在介绍了地磁匹配导航的基本原理的基础上,给出了地磁匹配系统的形式化模型。分析了影响地磁匹配导航精度的决定因素,最后从硬件和软件2个方面给出了提高其定位精度的途径。
The precision of a new navigation system--geomagnetic matching （GM） navigation was investigated. After the introduction of the basic principles of GM system, the formalized model of GM was given. Crucial factors affecting GM navigation precision was analyzed, and the ways, from the two aspects of hardware and software, to enhance the performance of GM navigation were proposed finally.
