| Abstract: | 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. |
