摘要
测控信息网能够为空间任务信息的获取、存储和分发提供统一的平台,能够
实现空间任务信息的统一管理、高效共享和综合利用。测控信息网是完成空间任
务的基础,空间信息传输协议是测控信息网的关键。随着我国载人航天工程和深
空探测工程的发展,特别是建设空间实验室和空间站目标的确定,为加快我国天
地一体化测控信息网络的建设,需要进行空间信息传输协的研究。
本文首先调研了现行国内外空间信息传输协议,提出在我国未来天地一体化
测控网中采用 IP over CCSDS 的传输协议体系。比较 CCSDS 数据链路协议和地面
商业数据链路协议,提出在 IP over CCSDS 协议体系数据链路层选择 CCSDS 协议
并给出了数据链路层协议配置的建议。然后介绍了常用的分包遥测、分包遥控和
高级在轨系统三种 CCSDS 空间数据链路协议。最后使用 OPNET 和 STK 仿真工具
对 CCSDS 协议进行了联合建模,主要仿真遥测协议和 AOS 协议的吞吐量性能。
通过建模仿真探讨了遥测协议和 AOS 协议包长、帧长、信道误码率的不同配置对
协议吞吐量性能的影响,并对仿真结果进行较详细的分析,得到的结论可以指导
协议在空间任务中的应用。

Abstract
Measurement and Control Information Network (MCIN) provides a unified
platform for space mission information acquisition, storage and distribution. It also
enables unified management of space mission information, to achieve efficient sharing
and utilization. Measurement and Control Information Network is the base of space
mission. Space information transfer protocol is the key factor of MCIN. With the
development of manned spacecraft mission and deep space exploration program,
especial the decision to launch space lab and space station, we need to speed up the
Measurement and Control Information Network duding and research the space
information transfer protocol.
This paper studies the current international and domestic space information transfer
protocols, and proposes the transfer protocol architecture based on IP over CCSDS that
fits the future development needs of MCIN of our country. Comparing the data link
protocols of CCSDS and commercial data link protocol, we choose CCSDS in data link
layer. This paper introduces TM, TC and AOS space data link protocols. At last, this
paper carries on the modeling and simulation to the CCSDS telemetry and AOS
protocol based on the OPNET and STK simulation platform and focuses on
