【摘要】：当前空间通信的发展趋势是空间通信网与地面通信网融合,建立天地一体化互联网络的信息传输系统。针对空间数据系统咨询委员会(CCSDS)推荐的基于CCSDS空间链路承载网际协议业务(IP over CCSDS)网关协议转换技术,文章提出一种实现天地一体化互联网络的航天器网关的设计思路,即通过研制航天器网关实现IP协议与CCSDS高级在轨系统(AOS)空间数据链路协议的相互转换,并对服务质量(QoS)保证方法进行了设计。针对航天器网络搭建了测试系统平台,并对高清图像、高质量话音、计算机数据和遥测数据等网络数据的传输进行了测试,测试中通过航天器网关进行传输的所有网络数据包均无丢帧现象发生,文章提出的IP over CCSDS网关可用于构建天地一体化互联网络。
[Abstract]:At present, the development trend of space communication is to merge space communication network with terrestrial communication network, and to establish the information transmission system of the earth and earth integrated internet network. In view of the technology of IP over CCSDS gateway protocol conversion based on CCSDS space link carrying Internet protocol recommended by the Space data Systems Advisory Committee, this paper puts forward a design idea of spacecraft gateway to realize the integration of space and earth network. Through the development of spacecraft gateway, the conversion between IP protocol and CCSDS spatial data link protocol is realized, and the QoS assurance method is designed. The test system platform is built for spacecraft network, and the transmission of network data, such as high-definition image, high-quality voice, computer data and telemetry data, is tested. In the test, all the network packets transmitted through the spacecraft gateway have not lost frames. The IP over CCSDS gateway proposed in this paper can be used to construct the integrated internetwork of earth and earth.
