摘要
近年来,国内外微纳遥感星座发展不断加速,通过高频重访大幅提升了对地观测的时间分辨率,但是由于单颗微纳卫星观测能力受限,难以满足多源同步与融合、高品质、大幅宽等数据应用需求。为此,将星座与星簇相结合,以星座化分布满足高时间分辨率需求,以星座节点上的星簇协同观测获取多源、高品质、宽幅数据,构建基于微纳卫星的分布式协同遥感系统,是兼顾上述遥感应用需求的有效途径。智能分布式协同控制是该系统的核心关键,为此,必须研究解决星座+星簇大规模动态微纳遥感星群控制系统的分布协同自主导航、智能运动规划与控制、智能健康预测与管理、智能组网等关键技术难题。在梳理分析国内外分布式微纳遥感系统的基础上,给出分布式协同微纳遥感星群的概念内涵,分析其特有的四方面难题,梳理总结相关技术发展现状与趋势,以期为后续该方向的研究起到一定的借鉴作用。
In recent years,the development of micro/nano remote sensing constellations has been continuous development.The time resolution of earth observation has been greatly improved through high-frequency revisiting.However,due to the limited observation capability of single micro/nano satellite,it is difficult to meet the data application needs such as multi-source fusion,high quality,and large bandwidth.In view of the aforementioned requirements,it is an effective way to build a distributed cooperative remote sensing system based on micro/nano satellites,in which the constellation distribution is used to obtain the high temporal resolution and the collaborative observation of star clusters on the constellation nodes is adopted to achieve multi-source,high-quality,and wide-format data.Since intelligent distributed cooperative control is the core of the system,it is necessary to study and solve the key technical problems such as autonomous navigation,intelligent motion planning and control,intelligent health management,and intelligent networking.In this paper,based on the analysis of recently distributed micro/nano remote sensing systems,the concept of distributed cooperative micro/nano remote sensing star cluster is provided.Four key technologies have been analyzed,to refine the development status and trends.The study could provide a reference for the follow-up relative research.
