基于OpenGL的空间探测器飞行轨迹可视化

在探讨了探测器轨迹的存储机制和实现方法的基础上,研究并实现了基于OpenGL的探测器在地心惯性系下的飞行轨迹、地面测控站的可见性轨迹、探测器相对于地球固连系的飞行轨迹以及探测器的星下点轨迹等多种轨迹的可视化。实际应用表明,这些可视化效果能表达各种不同的轨道信息,并使用户对探测器的飞行过程有全面、直观的认识。

Visualization of Space Probe Orbit Based on OpenGL

The storing mechanism and implementing method of space probe orbit are discussed,then based on OpenGL,many different types of space probe orbit are researched and realized,including orbit in ECI coordinate,visibility orbit of earth based control station,orbit in earth fixed coordinate and substar orbit.Practical use of this visualization method shows that it can express many kinds of orbit information,and also helps user to gain a complete and intuitive view of the flying process of space probe.
