摘要
讨论了基于卫星链路的双向实时数据和图像传输系统发展状况,并通过对系统的组成、系统的拓扑结构、数据传输协议的选择等方面的研究,提出了一个比较先进的系统设计方案。在此方案的基础上,建立了一个点对点双向实时传输模拟系统。所设计的系统在内部已构成了星型的网络结构,它们分别通过多路数据复用器和多路数据解复用器连接起来,并且通过多路数据复用器和多路数据解复用器与卫星通讯子模块相连,形成一个有机的整体,使系统具有广泛的应用范围。
The development status of the bi-directional realtime data and image satellite transmission system is introduced and then based on the research for the system constitution, the analysis for the system topology and the selection for the system transmitting protocol, an advanced designing program of bi-directional real time data and image satellite transmission system is developed and a point-to-point bi-directional realtime satellite transmission analogue system isrealized. Thedeveloped system is of starry network configuration, which can connect the satellite communication sub-module through the multiplexing data processing complex and the multiplexing data process- ing un-complex and is of vast applications.
