Abstract The generalized extension interpolation is used to interpolate the IGS precise ephemeris,and the interpolation accuracy and its relation with the three parameters are dicussed.The technique is compared with Lagrange polynomial interpolation and Chebyshev polynomial fitting. The results indicate that the generalized extension interpolation method is with higher accuracy.
Key words ：
generalized extension interpolation
Lagrange interpolation
