摘　　要：近年来,低轨大型遥感星座计划发展迅速,高频次、低成本、弹性高的大型低轨遥感星座系统成为了各国争相发展的技术。文章概述了Flock、Capella、BlackSky Global、Lemur-2、NewSat等低轨大型遥感星座的发展现状,以及中国大型遥感星座的基本情况;在此基础上,分别从遥感星座涉及的通信网络、自主协同、星座部署、星座管控、信息处理等5个方面,就低轨大型遥感星座涉及到的多载荷任务协同、星上自主任务规划、快速响应调度、星箭一体化设计、卫星星座构型设计、星座智能管控、遥感图像数据融合、星座数据处理等关键技术进行了总结分析,并对未来的发展趋势进行了阐述。In recent years, the large LEO remote sensing constellation project has developed rapidly. With high frequency, low cost and high flexibility, the large LEO remote sensing constellation system has become a technology that countries are competing to develop. Firstly, the development status of LEO large remote sensing constellations such as Flock, Capella, Blacksky Global, Lemur-2, Newsat and the basic overview of China’s large remote sensing constellations are summarized. On this basis, from the five aspects of communication network, remote sensing monitoring, constellation deployment in management and control, and information processing involved in the remote sensing constellation, the technologies involved in the LEO large-scale remote sensing constellation, such as multi payload task coordination, on-board autonomous task planning, rapid response scheduling, satellite rocket integration design, satellite constellation configuration design, constellation intelligent management and control, remote sensing image data fusion, constellation data processing, are summarized and studied, and its research direction is described.
