空间信息是指利用有效的信息承载工具,通过对空间站的信息进行有效的采集,传输到地面,供科研人员分析与探索,加强对科学研究的需要。空间信息的传递以互联网为媒介基础,将空间的卫星遥感技术、卫星导航技术和卫星通信技术结合为一体,形成基于应用与服务为一体的应用体系,实现对空间信息的收集与利用。本文针对目前我国空间信息网络发展的基本现状,提出具体的分析途径,从空间信息网络的概念和特点入手,结合国内外目前研制出的有效技术,形成我国空间信息网络构建过程进行有效的研究与分析。
Spatial information is the use of effective information-bearing tools, through the effective collection of information from the space station, transmission to the ground for scientific analysis and exploration, to strengthen the scientific research needs. The transfer of spatial information is based on the Internet. It combines space satellite remote sensing technology, satellite navigation technology and satellite communication technology to form an application system based on application and service, thus realizing the collection and utilization of spatial information. In this paper, according to the current situation of China’s spatial information network development, this paper puts forward specific analysis approaches. Starting with the concept and characteristics of spatial information network, combined with the effective technologies developed at home and abroad to form an effective research on the construction of China’s spatial information network analysis.
