摘要：This paper presents how Pléiades HR, the next French Earth Observation system which will succeed to SPOT 5, complementing it without replacing it, has been defined and decided. It describes the characteristics and performances of the system which will serve civilian and Defence applications and should be a key element for GMES and GEO initiatives., at European and International levels. From an user's analysis 10 new systems, based on small satellites, have been identified to fulfil most of the needs. After comparison, the highest priority was given to the development of high resolution systems, either with optical sensors or SAR instruments. Within a cooperative program, ORFEO, settled between France and Italy, high resolution SAR data should be provided by COSMO- SkyMed developed under Italian responsibility whilst high resolution optical images will be acquired by Pléiades HR, developed under French responsibility.. With its two satellites, to be launched in 2008-2009, Pléiades HR will provide high quality images, not only in terms of resolution (0.7 meter at nadir) but also in terms of MTF (0.2 at system level) and geometrical accuracy: Even without using any Ground Control Point absolute location accuracy should be better than 10 m. Orthorectified images will be produced as standard products for easier integration in Geographical Information Systems (GIS). The high agility of the platform and sensor will optimize acquisition of images either in stereoscopic or monoscopic mode on areas of very diversified sizes and shapes. A Preparatory Program has been undertaken with scientists, image processing specialists and end users in order to develop operational tools and methods for 2D or 3D applications of high resolution SAR and optical images
