论我国空间信息网络的构建

On Construction of China’s Space Information Network

  • 摘要: 空间信息网络是以空间平台(如同步卫星或中、低轨道卫星、平流层气球和有人或无人驾驶飞机等)为载体,实时获取、传输和处理空间信息的网络系统。空间信息网络通过组网互联,实时采集、传输和处理海量数据,实现卫星遥感、卫星导航和卫星通信的一体化集成应用与协同服务。介绍了空间信息网络的基本概念,分析了空间信息网络的主要功能和特点;在总结相关领域的国内外研究进展的基础上,论述了我国构建空间信息网络的重大意义,并对我国空间信息网络的研究目标和科学问题进行了论述。

     

    Abstract: Using space platforms as carriers,spatial information network(SIN)is a new kind of net-work system that implements real-time data acquisition,fast network transmission and informationprocessing.Through real-time data access/transmission,networks interconnection and cooperativedata processing,SIN could realize the integrated application and collaborative service of satellite re-mote sensing,satellite navigation and satellite communication.Firstly,the concept,function andcharacteristic of space information network are introduced.Then the significance and necessity of con-struction of China’s SIN are represented after an analysis of development of SIN at home and abroad.Finally,the research objectives and scientific issues for China’s SIN construction are discussed.
