Research and Realization on CCSDS Proximity-1 Link Space Protocol

为实现航天器间的近距通信,CCSDS提出近距空间链路通信协议。分析近距空间链路通信协议的应用场景、协议结构、协议特点及其通信流程,研究协议仿真软件的实现方法,提出基于C/C++语言的软件实现方案,使用MFC平台实现人机交互界面。该仿真软件实现了对协议通信流程的完备仿真,提供各个通信参数配置接口,作为仿真平台为应用层协议提供数据接口,可以进一步对整个协议栈进行性能测试。

To achieve the purpose of short-range communication between spacecrafts,CCSDS has referred proximity-1 link space protocol.The scenarios,architecture,characteristics and communication process of the protocol are analyzed in this paper.The implementation method of the simulation software based on C/C++ language is also proposed and the human-computer interaction is realized with the MFC tools.The simulation software can complete all the communication processes,and provide various interface for the configuration.Working as the simulation platform,it can provide the interface for the application layer protocol for the further research on the whole protocol stack performance.
