摘要
在空间近距操作仿真中,根据航天器飞行轨迹和外部环境因素的影响实时的仿真控制航天器的位置、姿态与特效是关键点。通过对航天器飞行轨迹的数字仿真数据和飞行过程中特效的研究,采用数字仿真数据作为飞行状态数据库,基于软件平台Creator和Vega开发出空间近距操作视景仿真系统。对该系统的设计和实现进行研究,通过系统总体框架和场景的几何建模及动力学建模,实现了追踪航天器从最初机动到最终逼近目标航天器以及完成操作的精确仿真,较好地解决了飞行中航天器的位置、姿态控制和各飞行阶段特效的生成等问题,具有较好的实时性。
It is the key point of proximity operation simulation to controll real time satellite＇s flight position, attitude and special effects according to satellite flight procedure and external environment influence. By researching the digital simulation program and special effect of flight procedure, and taking the real - time simulation data as the database of flight status, the visual simulation system of proximity operation in space is developed. The design and implementation of visual simulation of proximity operation is described, and some key technologies are introduced, such as geometric modeling and dynamical modeling, overlay area modeling, data driving to player. Finally, effects of the proximity operation visual simulation are given. The simulation results show that this virtual simulation system can well simulate the motion of proximity operation in space, with good real -time characteristics.
