本文重点介绍了如何通过GPS卫星星历来计算卫星的坐标，采用了直接法、拉格朗日插值法以及切尔比雪夫拟合的方法分析通过广播星历计算的精度-This paper focuses on how the GPS satellite has always calculate the coordinates of the satellite, using the direct method, Rugby Long Day interpolation Mitchell Chebyshev fitting m

计算方法实验作业，用java实现牛顿插值，拉格朗日插值，复化Simpson公式等-Compute the work, using java Newton interpolation, Lagrange interpolation, complex formulas, etc. of Simpson

差值算法，并且介绍了拉格朗日插值多项式，回复刚刚那个(The difference algorithm and the Lagrange interpolation polynomial)
