摘要
综述了国外商业遥感卫星发展情况,归纳总结了高分辨率商业卫星的主要技术指标和特点。在充分调研国外敏捷遥感卫星的基础上,从成像目标需求、分辨率与幅宽关系、立体成像三方面总结出此类卫星的技术特点,阐述了发展敏捷遥感卫星的重要意义和作用,并深入分析了实现姿态敏捷控制的技术途径。利用姿态的敏捷控制能力,研究提出了多点目标成像、立体成像、宽幅拼接成像、动态扫描成像等4种典型工作模式,完成了敏捷卫星主要工作模式的分析与设计,并基于此工作模式要求,提出了敏捷卫星工程实现的技术途径。
This paper introduces the developing trends of commercial remote sensing satellites,such as the Ikonos,GeoEye-1 from GeoEye Inc（USA） and QuickBird,WorldView-1,WorldView-2 satellites from DigitalGlobe Inc（USA）,and then analyzes and summarizes the specifications and characteristics of these commercial high resolution earth imaging satellites.On the basis of well researching on foreign remote sensing satellites,the technical characters of such kind of satellite are given out by considering the requirement of imaging target,stereo imaging and the relationship between resolution and breadth.It points out the effects and meaning of developing remote sensing satellites with agile controlling attitude,and analyses a solution of agile attitude control,according to the four main requirements： multi-point targets imaging,stereo imaging,wide piecing images and dynamically scanning imaging,the design and analysis of the main work modes for the agile satellite are completed.On the basis of the work modes,a technical approach for a swift satellite is given.
