Abstract: Consultative Committee for Space Data Systems(CCSDS) has proposed a series of standards on space communication protocol,such as Telemetry(TM),Telecommand(TC) and Advanced Orbiting System(AOS) standard.CCSDS space data system architecture and Space Communication Protocol Specification(SCPS) are analyzed in detail.Then an improved CCSDS transportation protocol scheme is proposed,including frame length and queue length optimization.Simulation results show that the proposed scheme can improve space data system throughput greatly,and can improve stability and end-to-end delay.
Key words: Consultative Committee for Space Data Systems(CCSDS), Space Communication Protocol Specification(SCPS), satellite network, inter-satellite link
摘要: 空间数据系统咨询委员会(CCSDS)为遥测、遥控和高级在轨系统(AOS)制定了一系列建议标准。分析了CCSDS空间通信系统体系结构,及空间通信协议标准(SCPS)协议体系,从帧长、队列长度两个方面,提出了一种CCSDS传输协议性能优化方案。仿真结果表明,优化后的空间通信协议大大提高了空间通信系统的性能,具有较高的吞吐率、较小的延时和更好的稳定性。
