基于SEP的卫星网络三维仿真系统的设计

中低轨道卫星网络现已成为当前卫星通信的发展方向,由于拓扑的复杂性和时变特性,高昂的造价和建造的复杂性使仿真成为研究工作必不可少的重要环节。介绍了自组织网络仿真平台（SEP,Self-organization network Emulation Platform）,该平台通过控制中心和终端节点的配合协作进行仿真,引入三维建模技术,研究建立了中低轨道卫星网络三维仿真系统。该系统能够动态显示中低轨道卫星组网以及整个网络路由的三维变化,具有较高的卫星网络仿真通用性,可为各种空间系统应用提供仿真测试环境。

Design of the 3D Simulation System of Satellite Network Based on SEP

LEO/MEO satellite network has become the direction of current research on satellite communication,and simulation is absolutely necessary because of topology complexiy and time variability,expense and infrastructure complexity.The 3D simulation system based on the self_organized network simulation plat is presented.The plat accomplishes the fuction of simulating by collaborative operations between the control-center and terminal nodes.It imports the technique of 3D modeling and set up the 3D simulation system of satellite network which has functions of demonstrating the 3D process of satellite network organization and the routing process.The system is highly universal in the satellite network simulation and can supply the test enviroment for sapce system applications.
