| Abstract: | The principles of Lagrange interpolation and Newton interpolation are described in the paper. And the first and second order differential coefficient once differentiation formulas of the two methods are derived. By the computation of satellite ephemeris data, the satellite acCeleration data is given. Test computation results showed the validity of the formulas and some beneficial conclusion. |
