摘要
对地观测系统和技术实现了全球实时的观测,在获取全球表面和深部的时空信息方面发挥越来越重要的作用,为环境监测和地球系统科学研究提供了基础条件。从对地观测卫星、传感器向高分辨率发展,对地观测卫星向网络化发展和对地观测系统向综合与协作发展3个方面论述了国内外对地观测系统未来发展的趋势,并从国家资助的角度、设备开发能力以及在其它领域的潜在应用价值、开发的成本、投入使用的时间需求等方面圈定了有限资助的技术范围,确定了未来对地观测在9个方面的技术需求。
Earth observation system and technology realized the global real-time observation and played an increasingly important role in acquiring space-time information of global surface and deep earth which provides condition for environment monitoring and earth system research. Development trend of earth observation system was discussed based on three aspects as high resolution development direction of earth observation satellites and sensors, networking earth observation satellites as well as integrated and coordinative development of earth observing system. At the same time, technology scopes and requirements were analyzed from the aspect of country investment, capabilities of equipments development and their potential application value in other fields, cost of development and operational needs of the time and so on.
