精密卫星钟差内插的埃尔米特方法

摘要

讨论了利用埃尔米特（Hermite）插值进行GPS精密卫星钟差的内插,并用实例数据进行了内插,即对5min采样率的IGS钟差文件,采用两点三次埃尔米特插值,能得到高精度和高分辨率的卫星钟差。%The theory and method of GPS precision satellite clock offset interpolation using Hermite were discussed in this article,and precision clock offset interpolation were done with the practice factual data,that is the 5-minute sampling rate clock offset files.High-precision and high-resolution satellite clock offset has been gotten using the two-point and cubic Hermite-interpolation.
