为了研究敏捷卫星大角度机动和推扫成像的方法和效能,分析成像工作模式、卫星参数和轨道参数,建立了基于MVC框架的敏捷卫星工作模式仿真系统。该仿真系统以VC2010作为开发环境,应用MVC框架技术构建系统各组成部分之间的信息交互,将仿真输出的卫星轨道数据、姿态数据和成像数据实时送入STK引擎,实现了敏捷卫星姿态切换和推扫成像过程的二维/三维实景可视化显示,对仿真的过程数据进行数据库存储,以供事后分析。经仿真验证,该系统实现了敏捷卫星工作模式方法和效能的交互式分析,可为敏捷卫星的总体设计方案提供支撑。
In order to study the method and efficiency of agile satellite wide-angle maneuvering and push-to-sweep imaging and to analyze imaging mode, satellite parameters and orbital parameters, an agile satellite working mode simulation system based on MVC framework was established. The simulation system takes VC2010 as the development environment and uses MVC framework technology to construct the information exchange between the various components of the system. The simulation output satellite orbit data, attitude data and imaging data are sent to the STK engine in real time to realize the agile satellite attitude switching and The two-dimensional / three-dimensional visualization of the push-to-scan imaging process shows that the simulated process data is stored in a database for later analysis. The simulation results show that the system can interactively analyze the method and performance of agile satellite working mode and provide support for the overall design of agile satellite.
