为卫星轨道拟合代码,根据两行轨道TLE参数拟合卫星位置-failed to translate

根据卫星的位置和速度，求取实时卫星轨道的两行根数，即6个开普勒根数。计算结果精度很高。-The position and velocity of the satellite strike two lines of the real-time satellite orbit root number, six Kepler root number. Calculation results of high precision.

利用SGP4模型读取TLE根数，并对卫星轨道进行预测(Using SGP4 / SDP4 model, the tle data, that is, the number of track elements in two lines, is read and the track is predicted.)
