摘要
利用Fortran语言编程实现了精密钟差文件的读取及信息筛选;在此基础上,利用滑动式Lagrange插值方法对精密钟差进行了加密,并对结果进行分析与讨论,得出了几点有益的结论。
In this paper,a subroutine program for reading a clock fil with Fortran was compiled.Moreover,sleek Lagrange fitting was take as a densification method to interpolate clock offset.Finally,results wer discussed and analyzed.
