可以实现快速傅里叶的计算，适用于matlab环境(Calculation can achieve fast Fourier for matlab environment)

作者在学习《航天系统》时，在c++6.0环境中实现的卫星定位的算法程序。包括通过轨道根数求卫星状态参数的算法和通过卫星状态参数反求卫星星历的算法。(Author of the study "space system" is in c++6.0 environment to achieve the satellite positioning algorithm. Including through the orbital parameters of the algorithm for the satellite status and Reverse status parameters via satellite satellite ephemeris algorithms.)
