摘要
使用Lagrange插值、Newton插值和Neville插值三种算法对IGS精密星历进行外推插值计算,通过实验得到,当插值方法为Neville法且插值阶数为11阶时运算精度和效率最优。
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.
