摘要
针对GPS精密星历插值精度,分别采用Lagrange、三次样条和Neville算法对GPS精密星历进行插值,综合比较了3种插值方法的适用范围,分析了适用于不同精度要求的GPS卫星轨道插值方法,为后续研究提供有益借鉴。
In view of GPS precise ephemeris interpolation accuracy, uses Lagrange, cubic spline and Neville algorithm interpolate GPS precise ephemeris and give a comprehensive comparison for the applicable scope of three kinds of interpolation methods. In addition, the applicable to different accuracy requirements of GPS satellite orbit interpolation method is analyzed, and a useful reference for follow-up study is provided.
