生动形象地刻画了地球的轨迹，以及模拟自传效益-Vividly depicts the Earth' s orbit, and the effectiveness of simulation autobiography

主要是利用matlab编程序来实现太阳与地球月亮的运行轨道。-Is to use matlab programmed to achieve the orbit of the Sun and the Earth moon.

火星-木星轨道的模拟，很有意思的一个东西-Mars- Jupiter orbit simulation, a very interesting thing

本代码用于模拟卫星星下点在地球表面上的投影。可以在程序中给定六要素及其他相关参数，就可以利用MATLAB呈现出仿真图。-The code for a simulated satellite point on the Earth' s surface projection. May be given in the program six elements and other relevant parameters, you can use MATLAB simulation showing
