    Abstract
  •     The cubic spline interpolation function is selected to calculate orbit data of the GEO or IGSO satellite in this article. The results of the cubic spline function do not show the runge phenomenon, but the interpolation model contains obvious randomness of the system error. So we take least squares configuration to process the result of the cubic spline interpolation.The result manifests that the accuracy is improved by more than about 10 times.
