    • Abstract
  • Due to the deficiency of moving Lagrange polynomial interpolation,a new interpolation method considering characteristic of satellite movement is introduced.The precisions of the two metho-dsis are compared by a numerical example.The analysis results show that the interpolation and extrapola-tion ability of the new method are better and its extrapolation precision is especially better than the conventional method.
