Abstract

Geomagnetic field is the basic physics field of the Earth, which can't be destroyed or changed in the foreseeable future. Geomagnetic field don't require special service, therefore, it can be considered as a solid source of navigation information. The key technologies of geomagnetic navigation are still looking for high accuracy mapping and high accuracy geomagnetic field measurement on board aircraft, The article analyses some kinds of geomagnetic models. according to the character of the geomagnetic models, The NGDC-720 model is used as reference map preparation. The model with Kriging method give birth to the reference maps which include geomagnetic seven vectors' map (X, Y, Z, F, D, I, H). Using the reference maps, The geomagnetic vectors'statistical characters have been analyzed. According to the statistical characters, some changeable obviously statistical characters can be used as matching characteristic values.
