摘要
CEOS虚拟星座通过相对独立空间资源的协同合作,实现统一标准下的全球持续、系统性观测,是空间资源合理高效运行的一种新思路。在回顾虚拟星座概念产生与发展的基础上,重点介绍了CEOS虚拟星座情况及进展,包括陆地表面成像、海面地形、大气成分、降水、海洋水色辐射测量和海面风矢量六大示范星座。最后,系统分析了虚拟星座当前发展存在的主要问题,并指出虚拟星座概念在我国空间对地观测领域的应用前景。
A CEOS Virtual Constellation is a set of individual space and ground segment capabilities operating together in a coordinated manner to implement the Earth Observation under uniform standards. The CEOS Virtual Constellation concept will provide a new approach to facilitate the rational and efficient operation of space resources. Based on the review of Virtual Constellation concept, this paper introduced the CEOS Virtual Constellation and the development of its six prototype constellations, which include Land Surface Imaging, Ocean Surface Topography, Atmospheric Composition, Precipitation, Ocean Color Radiometry,and Ocean Surface Vector Wind. Finally,the major problems of Virtual Constellation development are analyzed, and the application potential of the Virtual Constellation concept in our country＇s space-based Earth Observation field is pointed out.
