微小卫星对地观测及其应用前景

微小卫星技术是当今空间技术、电子技术、计算机技术、光学技术及遥感技术高度综合的结晶。目前,世界各国都在关注这项技术的发展与应用,以英国萨瑞大学空间技术中心为代表的国外对地观测民用卫星已为十几个国家进行小卫星及微小卫星研制及技术开发服务,我国有关部门已与萨瑞大学开展了有效的合作。从现有小卫星获取的数据资料质量及特征分析,其光谱及几何分辨率都较高,在全球灾害、环境监测、农业估产及资源调查等有广阔的应用前景。发展我国的微小卫星技术,将对我国航天遥感事业起到重要推动作用。

THE EARTH OBSERVING BY MICROSATELLITE AND ITS APPLYING PROSPECT

The technology of microsatellite is an important achievement of high integration of space technology, electronic technology, computer technology, optics technology and remote sensing technology, many countries, especially west countries are interested in its development and application. The Space Center of Surrey University of British has developed and designed more than 20 microsatellites for more than 10 countries. Some institutes of our country have a plan of cooperation with Surrey University in absorbing microsatellite technology. Through analyzing the imagery qualities and features of the data that acquired from microsatellite,authors consider it will have good prospects in global disaster and environmental monitoring, agricultural evaluation and resource survey in the near future. In China, developing itself microsatellite technology will have a strong promotion for its space remote sensing application in social sustainable development.
