Abstract :
Based on the influence of ionosphere on geomagnetic field, this paper tried to estimate the position of geomagnetic north-pole in geographic coordinates, via using GPS signal and Klobuchar model, and established the corresponding mathematical model. It is verified that the method is feasible by theoretical analysis and simulated data, and that the improved regional Klobuchar model and the perfection of the algorithm are in favor of the reliability and accuracy of the estimation of geomagnetic north pole.
