| Abstract: | On the basis of the influence of geomagnetic field on ionosphere,the position of geomagnetic north pole in geographic coordinates was estimated by using GPS signal and Klobuchar model,and the corresponding mathematical model was established.This method is validated to be feasible by theoretical analysis and simulated data,and it is further summarized that the regionalized improved Klobuchar model and perfect arithmetic will be in favor of the precision and reliability of estimating geomagnetic north pole. |
