The invention discloses a high-functional-density micro-nano satellite for monitoring low-orbit space debris. The satellite is composed of a turn-back type optical integrated structure, an expandable double-layer film sensor, a satellite-borne real-time processing system, a solar panel and a modular CubeSat component. The turn-back type optical structure comprises a satellite 3U main frame and an optical system and forms a main body structure of the satellite, one third of the main body structure is the turn-back type optical structure, the design ensures that the proportion of the optical system is maximized in a limited volume, and a large field angle and high optical observation capacity are achieved; the expandable thin film sensor is stored in a cubic satellite body, after a satellite enters an orbit, the expandable thin film sensor is released, expanded and used for monitoring space tiny dust, the folding-unfolding ratio is large, and the expandable thin film sensor is suitable for the limited space of a micro-nano satellite; the satellite-borne real-time processing system is composed of a core processor and a peripheral circuit and has real-time image processing and data downloading capabilities; and the other components jointly maintain the attitude stability and normal operation of the satellite.

    一种用于低轨空间碎片监测的高功能密度微纳卫星。该卫星由折返式光学一体化结构,可展开式双层薄膜传感器,星载实时处理系统,太阳帆板与模块化CubeSat部件组成。折返式光学结构包括卫星3U主框架和光学系统,构成卫星的主体结构,其中三分之一为折返式光学结构,该设计保证了在有限体积内最大化光学系统占比,具有较大的视场角与较强的光学观测能力;可展开式薄膜传感器收纳在立方星体内部,卫星入轨后将释放展开并监测空间微尘,折展比大,适应于微纳卫星的有限空间;星载实时处理系统由核心处理器及外围电路组成,具有实时图像处理与数据下传能力;其余组成部件共同维护该卫星的姿态稳定与正常运转。
