低轨卫星通信网络半实物仿真系统构建与实现

Construction and Implementation of Hardware in Loop Simulation of Low Earth Orbit Satellite Communication Networks

为了测试低轨卫星通信系统的软硬件性能以及对系统进行整体优化,通常的做法是构建半实物仿真系统。首先分析用OPNET进行半实物仿真的基本原理,在此基础上搭建低轨卫星通信网络半实物仿真系统,将OPNET软件仿真系统和硬件处理模块结合起来,测试抗毁路由、负载均衡等处理流程以及时延、丢包等系统性能,为系统的整体性能优化以及卫星通信网络的实际运用打下基础。

For low earth orbit satellite communication network,in order to test the performance of hardware and software of the system and optimize the system as a whole,the usual way is to build a hardware in loop simulation system.First of all,the basic principles of hardware are analyzed in loop simulation with OPNET.And then hardware is built in loop simulation of LEO satellite communication networks,combined with the OPNET software simulation system and hardware processing module.At last,the processing of invulnerable routing,load balancing and delay,packet loss and other system performance are test,and the foundation is achieved for the overall performance optimization to the system and the practical application of satellite communication network.
