The SITAN algorithm makes use of terrain elevation information to aid inertial navigation system and achieves good results. The geomagnetic field can be used as the conditions of the auxiliary inertial navigation, because the geomagnetic value map and the terrain elevation map have high similarity. By using the SITAN algorithm and combining the contour information of existed geomagnetic map with the processed by the method of interpolation and linear processing at the same time, the aid inertial navigation simulation was carried out for the measured geomagnetic map to provide reference for a new passive and covert method of geomagnetic field aided navigation.
