摘要
近三年来，微纳卫星在通信、遥感、导航领域的发展令人瞩目。本文在系统回顾微纳卫星的定义、应用特点和国内外发展现状的基础上，从提高影像获取的时间分辨率和丰富数据获取手段两个方面分析了微纳卫星的摄影测量应用需求，然后从星座设计和定位能力两个方面分析了实现上述两个需求的可行性，提出了“大小微并举、高中低互补”的测绘卫星体系优化设计思路。
In the past three years, micro/nano satellites have made a remarkable advancement in the fields of communication, remote sensing and navigation, Based on the definition, application characteristics and development status of micro/nano satellites, the photogrammetric application requirements of micro/nano satellites are analyzed from two aspects ： the first is to improve the image acquisition resolution, and the second is to enrich the data acquisition means. Then the feasibility of satisfying the requirements is analyzed in terms of constellation design and positioning ability, and a surveying and mapping satellite system optimized designing idea that ＂develop large, small and micro satellites together in high, medium and low orbit＂ is proposed.
