Abstract Both the characteristics of Lagrange interpolation and Neville interpolation are compared with each other. It is concluded from the results that the highorder interpolation is not good enough for highprecise applications.Finally, a new interpolation method which based on high/low orders to solve this problem is put forth.
Key words ：
GPS
precise ephemeris
Lagrange interpolation
Neville interpolation
different orders
