Abstract :
In order to improve the poor accuracy and stability of the traditional geomagnetic matching navigation by TERCOM, In this paper, we discuss a new method which is based on the integration of TERCOM, K-means clustering algorithm and INS (inertial navigation system) in detail. Through an experiment, we find that the new method has higher accuracy and stability than the traditional method, especially when it is used in the similar geomagnetic distribution area.
