精密星历内插的比较分析
首发时间:2011-03-18
摘要:IGS提供的精密星历间隔为15min,而在GPS精密单点定位解算过程中,需要更小的时间采样率的观测数据,此时要求对精密星历进行内插。因此本文分别采用拉格朗日插值、牛顿插值对GPS卫星轨道进行插值,并对这两种插值的特性和插值结果进行比较分析,得出一些结论。

Comparative Analysis Of Precise Ephemeris Interpolation
Abstract:IGS provided precise ephemeris interval of 15min, in the GPS Precise Point Positioning Solution process, the need for a smaller time sampling rate of observational data, when requested to carry out precise ephemeris interpolation. Therefore, this article using the Lagrange interpolation, Newton interpolation of the GPS satellite orbit interpolation, and interpolation of these two characteristics and comparative analysis of interpolation results, draw some conclusions.
