摘要
为解决全球高光谱遥感数据稀缺问题,需研究具有快速响应能力的高光谱卫星技术。分析了高光谱卫星发展现状和趋势,提出了微小型高光谱载荷配置方法,并在此基础上进行观测任务需求分析。通过提出的基于通用接头的分舱式模块化设计方法、低冲击的小型化在轨展开技术、智能化的在轨自主工作模式,实现了微纳卫星的模块化、小型化、智能化设计。在轨试验结果表明,提出的微纳卫星具有应对突发情况的快速响应能力,在国际上首次实现了50 kg以下卫星的高光谱遥感观测。
To solve the problem of global hyperspectral remote sensing data scarcity,it is necessary to study hyperspectral satellite technology with rapid response ability.The present situation and trend of the development of hyperspectral satellites were analyzed,and the configuration method of small hyperspectral payload was proposed,that requirements analysis for observation missions has been completed.The modular,miniaturized and intelligent design of micro-nano satellite has been realized through the subdivision modular design method based on universal joint,the miniaturized in-orbit deployment technology with low impact and the intelligent in-orbit autonomous working mode.The in-orbit test results show that the proposed micro-nano satellite has the ability to rapid respond to emergencies.It has achieved the hyperspectral remote sensing observation of the satellite below 50 kg for the first time in the world.
