Read of Precise Ephemeris File and Research on Methods of Interpolation
摘要
Abstract
This article had completed the read and information calendar of precise ephemeris file by using Matlab.In the process of PPP,it needs to observe data of precise ephemeris whose time interval is less than 15 min,so two methods of interpolation are introduced in the article： Lagrange and Newton.Insert in the precise ephemeris,and comparative analysis on the results of interpolation,so that we can get some beneficial conclusions.关键词
