Study on Simulation Technology of Agile Satellite Working Mode Based on MVC

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。

To study on the method and effectiveness of large angle maneuver and push broom imaging for agile satellite, an agile satellite working mode simulation system was established based on MVC though analyzing imaging model, satellite parameters and orbital parameters of ＂Quickbird2＂, a high resolution of commercial remote sensing satellite in the United States. The simulation system took VC2010 as software development environment, adopted MVC framework technology to realize information exchange between various members of the system, put satellite orbit data, attitude data and imaging data of simulation output into STK engine to realize 2D/3D scene visualization of agile satellite attitude switching and push broom imaging, the process data of simulation were stored in database for post analysis. The simulation results show that the simulation system realizes the interactive analysis of the working mode and the effectiveness of agile satellite, and can provide support for the overall design of the agile satellite.
