This paper introduces the first ESA Core Earth Explorer mission, GOCE, in the context of ESA's Living Planet programme. GOCE
will measure highly accurate, high spatial resolution differential accelerations in three dimensions along a well characterised
orbit: the mission is planned for launch in early 2006. The mission objectives are to obtain gravity gradient data such that
new global and regional models of the static Earth's gravity field and of the geoid can be deduced at length scales down to
100 km. These products will have broad application in the fields of geodesy, oceanography, solid-earth physics and glaciology.
This revised version was published online in August 2006 with corrections to the Cover Date. 相似文献

近年来,国内外微纳遥感星座发展不断加速,通过高频重访大幅提升了对地观测的时间分辨率,但是由于单颗微纳卫星观测能力受限,难以满足多源同步与融合、高品质、大幅宽等数据应用需求。为此,将星座与星簇相结合,以星座化分布满足高时间分辨率需求,以星座节点上的星簇协同观测获取多源、高品质、宽幅数据,构建基于微纳卫星的分布式协同遥感系统,是兼顾上述遥感应用需求的有效途径。智能分布式协同控制是该系统的核心关键,为此,必须研究解决星座+星簇大规模动态微纳遥感星群控制系统的分布协同自主导航、智能运动规划与控制、智能健康预测与管理、智能组网等关键技术难题。在梳理分析国内外分布式微纳遥感系统的基础上,给出分布式协同微纳遥感星群的概念内涵,分析其特有的四方面难题,梳理总结相关技术发展现状与趋势,以期为后续该方向的研究起到一定的借鉴作用。 相似文献
