Application of geomagnetic field in navigation and localization system

Yuze Li

Abstract

The geomagnetic navigation principle and geomagnetic theory was explained,and the development of geomagnetic navigation in the world was introduced.Three crucial technologies including modeling regional geomagnetic field model,geomagnetic measurement at real-time,and geomagnetic matching algorithm were put forward.Meanwhile,the main problems in geomagnetic navigation system were analyzed,and the necessary methods for developing geomagnetic navigation were pointed out,which clearly show the way to the further research.
