| Abstract: | The principle of Lagrange interpolation,Newton interpolation and Neville interpolation were analysized to predict the lacation of GPS satellite with IGS precise ephemeris.Based on the experiment,the conclusion is obtained,when the interpolation algorithm is Neville and the order of interpolation is 11,the precision and efficiency are optimum. |
