摘要: 卫星在轨运行的可视化仿真,能够直观、逼真反映卫星的实时轨道和姿态运动。卫星工具软件包(STK)是进行卫星系统仿真和分析的重要工具,能够满足卫星二维和三维的可视化仿真要求。在深入研究STK/Connect模块的基础上,应用Windows Sockets和多线程编程技术,开发了STK实时视景仿真驱动程序,该程序利用UDP协议接收模拟遥测计算机给出的卫星参数,通过与STK/Connect模块的通信,实时驱动STK的仿真运行,成功实现了卫星在轨运行实时视景仿真的演示效果。

Abstract: Visualization simulation of satellite orbiting the earth can display the satellite’s orbit and attitude motion intuitionisticly and really. The STK is an important tool for satellite simulation and analysis. It can display 2D and 3D graphics of the satellite. This paper studies the core technique of STK/Connect, makes use of the windows sockets and multi-threads programming technology, and develops the drive program for STK realtime visualization simulation. This drive program receives the data from the telemetry simulator computer according to the UDP protocal, then drives the STK runing through communicatting with the STK’s connect module. Results show that the drive program can realize the realtime simulation for satellites.

Key words: visualization simulation, STK, multi-threads, satellite
