摘　　要：针对航天器飞行及测控过程可视化问题,系统在设计、发射、运行管理、作战分析等各个阶段都起着重要的作用。为了直观准确地设计飞行器系统,采用可视化工具Vega Prime和开放图形库OpenGL,设计了航天器飞行及测控过程可视化系统,其功能包括实时显示地球、航天器和星空背景等空间对象运动变化过程,动态显示航天器轨迹、覆盖范围、测控设备跟踪测控和测控范围等本身不可见对象,以及多视点观察和多场景的融合等,并进行仿真试验。结果证明,系统不仅可视化效果形象逼真,而且具有开发周期短的优点。Visual simulation of spacecraft motion and TTC plays an important role in all phases of spacecraft system such as designing,launching,motion managing and operational analyzing.Integrating the merits of Vega Prime and OpenGL,the paper designs and implements the system of visual simulation of spacecraft motion and TTC,which includes exhibiting the moving variation of earth,spacecraft and star-back,displaying spacecraft orbit covering area,tracking TTC and TTC range which can not be seen originally,view point controlling and scene syncretizing.The simulation results show that the system is visual and realistic,while the system exploitation period is very short.
