摘要
空间通信链路由于其固有的特点(长传播延迟、可变延迟和高误码率),对空间通信的服务质量QoS(Quality of Services)提出了新的要求和挑战.提出了空间通信系统模拟的体系结构,实现了基于卫星工具包STK(Satellite Toolkit)的空间通信系统的模拟,并开发了空间通信系统的QoS性能测量软件;同时对QoS性能进行了分析.
Abstract challenges emulation Because of its inherent characteristics, on the QoS (Quality of Services) of space of space communication system and achieves space communications link raises new requirements and communications. This paper suggests an architecture for the its implementation with STK (Satellite Toolkit). Meanwhile,we develop QoS performance measurement software for space communications system and analyze the QoS performance of the proposed architecture.
