| Abstract: | Geomagnetic field is the natural resource surrounding the earth, and geomagnetic navigation is a novel navigation technology. Compared with the inertial navigation and the satellite navigation, the geomagnetic navigation has advantages of no error accumulation, strong anti-interference, good concealment and rich information. In this paper, we introduce three key factors in geomagnetic navigation, namely the measurement method for magnetic field, the geomagnetic model and the method for positioning and navigation. The application in geomagnetic navigation and the characteristic of magnetometer are analyzed. The geomagnetic model and the navigation arithmetic are discussed in detail. It is shown that the geomagnetic navigation is a promising navigation technology and has wide market in the future |
