精密卫星钟差内插方法研究
isscussion on Satellite Clock Error Interpolation Method
本文主要介绍了精密单点定位中的精密卫星钟差插值的问题，利用IGS提供的精密卫星钟差，分析和比较利用滑动式拉格朗日插值、线性插值以及三次样条插值三种不同的插值方法，分别通过对15min和5min间隔的卫星钟差进行内插。通过实验分析，取得了一些精密卫星钟差插值的有益结论和建议。
his paper briefly introduces satellite clock bias interpolation in precise point positioning, and sliding Lagrange interpolation, linear interpolation and cubic spline interpolation are taken to study on the densification of IGS satellite clock bias with 15min and 5 min intervals. After comparison, the results show that satellite clock bias interpolated from 5min interval data by linear interpolation has good performance.
