The invention discloses an on-orbit spacecraft fault diagnosis and long-term state monitoring method. Comprising the following steps: performing health diagnosis on an on-orbit spacecraft by utilizing a configured three-dimensional reconstruction camera and an optical camera in a flying-around process of a micro-nano satellite; if the health is damaged, an adsorption stopping position is selected; the micro-nano satellite is close to the adsorption stopping position so that the adsorption load can be in contact adsorption with the adsorption stopping position; after adsorption, the micro-nano satellite is separated from the adsorption load, the micro-nano satellite executes other tasks, and the adsorption load stops for a long time to monitor operation information and orbit information of the on-orbit spacecraft. The method is economical, credible and efficient, the problem that the protection capacity of the on-orbit spacecraft is insufficient is solved, the safety of space asset operation is improved, and the method can be used as a typical protection application method of the on-orbit spacecraft.

    本发明公开了一种在轨航天器故障诊断与长期状态监测方法。包括:微纳卫星绕飞过程中,利用配置的三维重建相机和光学相机对在轨航天器进行健康诊断;若健康受损,则选取吸附停靠位置;微纳卫星抵近吸附停靠位置以使吸附载荷与吸附停靠位置接触吸附;吸附后微纳卫星与吸附载荷脱离,微纳卫星执行其他任务,吸附载荷在长期停靠以监测在轨航天器的运行信息和轨道信息。该方法不仅经济、可信、高效,而且弥补了在轨航天器防护能力不足的问题,提高了空间资产运行的安全性,可作为在轨航天器的一种典型防护应用方法。
