摘要
综述了美国DigitalGlobe公司的QuickBird,WorldView-1,WorldView-2卫星和GeoEye公司的IKONOS,GeoEye-1,GeoEye-2等卫星的发展概况。分析评论了这些不同发射时间和使用年代的近代高分辨地球成像商业卫星及其空间相机的主要技术指标和特点,指出了研制小型、灵巧性卫星是近代高分辨地球成像商业卫星的发展趋势,其中需要解决的核心技术主要包括卫星的精密姿态控制、小像元尺寸和高积分级数TDICCD的研制,小相对孔径光学系统的设计以及用于图像增强的数字图像处理技术等。
This paper introduces the developing trends of QuickBird, WorldView-1, WorldView-2 satellites from DigitaleGlobe Inc （USA） and the IKONOS, GeoEye-1, GeoEye-2 satellites from GeoEye Inc （＇USA）, and then analyzes and reviews the specifications and characteristics of these high resolution earth imaging commercial satellites and their space cameras at different launch schedules. It points out that the development of earth imaging commercial satellites will trend towards small volumes and smart performance. Therefore, the next research should focus on the attitude control of satellites precisely, exploration of TDICCD with small pixel sizes and high integrated orders, design of optical systems in small related apertures and digital image processing technology for image enhancement.
