gps卫星中利用精密星历文件提供的钟差信息没差出任意时刻的钟差值-gps satellite ephemeris file using precision clock error information provided at any time without deviation from the clock difference

LANGAUGE，可以用在GPS轨道拟合和卫星钟差拟合等场合，算法简单，值得尝试-LANGAUGE, can be used in GPS orbit fitting and satellite clock error fitting occasion, algorithm is simple, is surely worth a try

SUBHERMITE，可以用在GPS轨道拟合和卫星钟差拟合中，可以很好的解决hermite的runge现象，有兴趣的可以参考-SUBHERMITE, can be used in GPS orbit fitting and satellite clock error fitting, can well solve the Hermite runge phenomenon, interested can refer to

HERMITE插值，用在gps轨道内插和卫星钟差内插的场合，有兴趣的可以和subhermite比较下-HERMITE interpolation, interpolation used in GPS orbit and satellite clock difference interpolation, interested can and subhermite comparison
