Paper 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, this paper special attention is paid to the data grid interpolation methods, the absolute accuracy of the interpolation methods are analyzed by comparing interpolation point with the actual surveyed point, and the geomagnetic map grid interpolation methods can be evaluated impersonally by residuals analysis. The results show that Radial Basis Function Method has little standard error, little average deviations and little standard deviations, and it has little "bull's-eyes" in the geomagnetic map.
