RESEARCH ON GPS PRECISE EPHEMERIS INTERPOLATION BASED ON HIGH/LOW ORDERS INTEGRATED
基于阶次组合的GPS精密星历插值研究

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