A Visual Simulation System for Spaceflight Mission Based on STK/VO

该文在STK/VO的基础上构建了一种适于航天任务的视景仿真系统,目的在于为航天任务的分析与设计提供一个直观的可交互的可视化仿真环境。该系统引入了资源库,对仿真所需的场景、模型等资源提供了有效的管理;同时还提供了模型的离线、在线编辑和场景显示属性的实时控制等功能,使仿真场景更加逼真生动;并提供了与应用仿真模块的接口,使系统具有通用性和可重用性。该文在描述系统结构与功能的基础上,重点介绍了航天任务仿真的三维建模、编辑及显示控制,最后以一个应用实例具体说明了系统各模块的功能及仿真流程。

Based on the principle and applications of STK/VO, the structure of a visual simulation system suitable for spaceflight mission is presented in this paper. The system is expected to provide an intuitionistic and interactive visual simulative environment for the analyses and design of spaceflight mission. A resource database is included in the system, which provides effective management of the resource needed by the simulation such as the scenarios and models. The system provides the abilities to edit the models inline and outline and to control the visual attributes of the scenarios in real time. These abilities make the simulation scenarios more realistically and more lively. An interface to the applied simulation modules is also provided in the system, which makes the system able to generally used and reused. After the description of the configuration and functions of this system, the three - dimensional modeling and editing and the visual control are presented as the emphases. At the end of this paper, an application example is raised to describe the functions of every module and the simulation process concretely.
