Proba-3太空任务实现毫米级精确编队飞行Proba-3 space mission achieves precise millimetre formation flying
➀ 欧洲航天局Proba-3任务成功实现两艘航天器（日冕仪与遮星板）的毫米级精确编队飞行，在无地面控制下自主保持150米间距数小时；
➁ 任务通过遮星板的1.4米圆盘投射阴影至日冕仪的光学设备，以研究太阳日冕，依赖激光计量、光学追踪和AI算法实现精准定位；
➂ 项目由ESA主导，MDA Space、空客防务与航天等企业及比利时科研机构参与，采用高精度激光传感器（FLLS）和阴影定位技术确保毫米级对齐。
➀ The European Space Agency's Proba-3 mission achieved millimeter-precision formation flying between two spacecraft, the Coronagraph and Occulter, maintaining a 150-meter separation autonomously for hours;
➁ The mission aims to study the Sun's corona by aligning the Occulter's 1.4m disc to cast a shadow onto the Coronagraph's instrument, enabled by laser metrology, optical sensors, and AI-driven algorithms;
➂ Key contributions came from ESA, MDA Space, Airbus Defence and Space, and Belgian institutions, with advanced technologies like the Fine Lateral and Longitudinal Sensor (FLLS) ensuring millimeter accuracy.
