空间碎片环境动态可视化软件开发

Dynamic Visualization Technologies for Space Debris Environment

对国内外空间碎片环境模型进行比较分析,设计了空间目标仿真显示系统,构建了空间碎片环境演化的可视化平台,利用OpenGL的纹理、双缓冲等技术实现了空间环境场景元素的绘制及动态显示。系统可以根据TLE轨道参数,利用SGP4轨道预报模型,或给定开普勒轨道参数,利用其它解析轨道理论,实现对空间碎片轨道运动的动态显示。对Iridium 33与COSMOS 2251碰撞事件进行了再现,相关技术已用于空间目标天基光学监测与编目仿真系统,动态展示空间目标监测与轨道编目的进程。

Based on the comparative analysis of the existing space debric environment models.A simulation display system for space objects is designed,and the visualization platform of space debris environment evolution is constructed.The drawing and dynamic display of space environment scenes are realized by OpenGL texture and double buffering tools.The system can use the TLE parameters/SGP4 orbit prediction model given kapler orbit parameters,or other analytic orbit theory,to demonstrate the dynamic display of space objects.Based on this system,the Iridium 33 and COSMOS 2251 collision event is represented and studied.Relevant fechnologies have been applied in the space-based optical surveillance and simulation system of cataloguing of space objects,dynamic display of spatial object surveillance&catalognis of orbits.
