摘　　要：针对卫星运行可视化仿真中卫星的姿态控制问题,设计出一种基于Open Inventor的卫星运行姿态控制可视化仿真系统。介绍了通过平移,旋转等坐标变换实现卫星模型处于二体定向姿态的思路和算法,二体定向姿态即有效载荷面对准地球以利于科学探测,太阳帆板跟踪太阳以保持供电。提出了基于Open Inventor的具体实现算法,充分利用Open Inventor的功能特点,卫星建模时增加了太阳能电池板绕中心轴向的旋转自由度,简化了算法。仿真结果表明,该系统能够较好地满足系统仿真的实时性要求。描述的思路和算法对构建航天可视化仿真系统具有一定的借鉴意义。According to the problem of satellite attitude control in visual simulation, a visual simulation system of satellite attitude control based on Open Inventor is designed. The method and algorithm of satellite attitude control are introduced which are realized by translation and rotation to achieve the satellite model in two- axis - oriented attitude. The two- axis - oriented attitude that is the payload face to the Earth in order to facilitate scientific exploration and the solar panels track the sun in order to maintain power. Take full advantage of Open Inventor, the solar panels increase the rotation around the central axis to simplify the algorithm in satellite model. The simulation results show that this visual simulation system can meet the real time requirement. The method and algorithm can be useful for developing aerospace visual simulation system.
