本人的呕心力作：角速度匹配传递对准matlab程序！绝对没有问题，先运行1，再运行2！(Nausea my works: angular velocity matching transfer alignment procedures matlab! Absolutely no problem to run 1, run 2!)

使用SGP模型进行轨道计算的matlab源码 使用两行星历TLE(Simplified perturbations models are a set of five mathematical models (SGP, SGP4, SDP4, SGP8 and SDP8) used to calculate orbital state vectors of satellites and space debris relative to the Earth-centered inertial coordinate system. This set of models is often referred to collectively as SGP4 due to the frequency of use of that model particularly with two-line element sets produced by NORAD and NASA.)
