本程序实现神州飞船跟踪测控的计算机虚拟，动画中地球、飞船和地面12个测控站同时运动。本程序是有声动画的仿真，使用时只要把bhk_med.wav文件放在D盘里然后运行该程序就Okay了(The Shenzhou spacecraft tracking and control program to achieve a virtual computer, the animation of the Earth, spacecraft and 12 ground control stations at the same time exercise. This program is a sound animation of the simulation, when used as long as the bhk_med.wav file on the D drive in and then run the program on the Okay a)
