The invention discloses a space microdebris monitoring micro-nano satellite based on a double-layer film sensor. The satellite performs two-way verification through non-vision in-situ measurement of the double-layer film sensor and vision measurement of the monitoring camera, and monitors space tiny debris with the size smaller than 1cm, so as to obtain data information such as velocity vector of the debris, and provide real-time and accurate tiny debris cloud data. The normal direction of the satellite film is the same as the satellite speed direction, and the probability of collision monitoring between the satellite and the space tiny debris is increased. An innovative folding and unfolding mechanism is adopted, the double-layer film sensor is small in folding size and convenient to unfold, and the double-layer film sensor can be used as a fragment monitoring device and a satellite deorbit device commonly installed on a micro-nano satellite module and has double functions. An innovative locking-releasing mechanism is adopted, locking of the whole mechanism can be achieved only through small pre-tightening force, meanwhile, separation impact can be reduced to the minimum through the rope burning releasing design, and the stability and safety of the system are improved.

    一种基于双层薄膜传感器的空间微小碎片监测微纳卫星。该卫星通过双层薄膜传感器的非视觉原位测量和监视相机的视觉测量进行双向验证,进行对尺寸小于1厘米的空间微小碎片的监测,以获得碎片的速度矢量等数据信息,提供实时、精确的微小碎片云数据。卫星薄膜的法向与卫星速度方向相同,增加了卫星与空间微小碎片碰撞监测的概率。本发明采用创新的折叠展开机构,双层薄膜传感器折叠体积小、展开方便,可作为微纳卫星模块普遍安装的碎片监测装置兼卫星离轨装置,具有双重功能。本发明采用创新的锁紧‑释放机构,只需较小的预紧力即可实现整个机构的锁紧,同时其烧绳释放的设计可将分离冲击降至最低,提高系统的稳定性和安全性。
