摘要
传统的航天工业仿真技术主要用于分析计算航天器的飞行轨道与姿态运动,这种仿真方式通常不支持三维可视化仿真功能;文章结合卫星轨道、姿态动力学和计算机图形学,设计基于三维实时动态显示技术的小卫星在轨运行仿真系统,对卫星轨道、姿态进行可视化仿真,实时动画演示星内敏感器的工作状态,提供图形曲线和文本形式的分析数据,并能与卫星地面站进行数据通讯,实现小卫星的在轨监测功能;仿真结果表明,仿真系统能正确实时接收地面站的数据,支持二维、三维动画输出,可以成功完成小卫星系统的仿真与监测功能。
Traditional simulation technology in aviation industry is mainly applied for analysis of orbit and attitude of satellites, often lack of 3D visual simulation function. A simulation system of in-orbit small satellite movement is designed combining computer graphics, which can support orbit and attitude animation of small satellite and display the working status of sensors inside. The result shows that the simulation system can receive data from facilities correctly, with the output of 2D and 3D animation vivid and real-time. The system accomplishs the simulation and supervision function successfully.
