摘　　要：设计了适合星间激光链路的零相位因子LEO/MEO双层卫星光网络结构。基于稳定拓扑双层卫星光网络提出了实验室仿真演示系统构想。演示系统分为实际网络和虚拟网络两部分,由OPNET提供虚拟仿真环境,利用移动无线激光通信模拟卫星光网络时变拓扑。最后利用SITL(System-in-the-Loop)模块将两部分网络互联实现交互式仿真。A double layer optical satellite networks of LEO/MEO with zero phasing factor is designed which adapts to laser inter-satellite links. A sketch of system in laboratory of simulation＇and demonstrating verification is developed based on stabilized physical topology .The system is divided into two parts, real network and simulated network. Simulated work is offered by OPNET, and the mobile wireless laser communication simulates the time-variable topology of the optical satellite networks, the two parts are connected by SITL （System-in-the-Loop） so as to achieve interactive simulation.
