The precise measurement of the geomagnetic element is the key to realize navigation and positioning with the development of geomagnetic navigation technology. In this paper, a kind of underwater vehicle three-component geomagnetic field differential measurement method is presented based on the ideas of the difference. The threecomponent geomagnetic field mathematical model of traditional measurement method is improved and new differential measurement model(DMM) is established. Difference expressions of measurement magnetic field in the DMM obviously reduce the impact of interference magnetic field in the process of geomagnetic field measurement and improve the measuring precision of the three-component geomagnetic field. Finally, the method’s effectiveness is validated by simulation. The precision of DMM method is 10 ± 5nT which is about two times that of traditional measurement model (TMM) method under the condition of ± 25nT stray outside interference magnetic field. The method effectively improves the geomagnetic field measurement precision and has stronger antiinterference ability. It is of significance for practical application of underwater geomagnetic navigation method.
