基于OpenGL的空间目标观测可视化仿真

Visual Simulation of Space-objects Observation Based On OpenGL

对空间目标运行态势的可视化,一直是备受关注的问题。对于两行轨道根数(TLE)文件,研究了如何根据SGP4/SDP4模型计算空间目标的轨道数据。详细说明了可视化仿真的关键技术:运用OpenGL图形库绘制空间目标的三维模型和覆盖区域,分析多视图间同步控制机制。最后实现了可视化仿真,试验员可以通过多个视图观测空间目标运行态势。

The problem of Space-objects＇ visualization has been highly concerned for years. How to use SGP4/SDP4 model was studied to calculate the spaces-objects＇ orbit data with the TLE file. The key techniques of simulation were introduced in detail： by using the OpenGL Library, the drawing of three-dimensional objects and the cover of the space-objects, and the synchronous control mechanism of multi-views were analyzed. The visual simulation was realized at last, Experimentalists can observe space-objects running situation in different points of view.
