摘　　要：非受控航天器抢救是保护空间资产的重要手段之一,分析并确定目标的姿态运动状态对于失效航天器抢救十分重要。本文针对非受控航天器姿态运动及相关影响因素进行了梳理和总结,分析了空间环境干扰和航天器组件干扰的影响效果,并以SAST-1000平台为例,对以上干扰影响进行了综合分析,给出了特定情况下航天器的姿态运动模型简化方案和不同扰动对于动量矩和转动动能的影响情况。Uncontrolled spacecraft salvage is one of an important means of protecting space assets,and analysing and determining the target attitude motion state is very important for failed spacecraft salvage.This paper provides an overview and summary of uncontrolled spacecraft attitude motion and related influencing factors.The effects of space environment interference and spacecraft component interference are analyzed.Taking the SAST-1000 platform as an example,a comprehensive analysis of the effects of the above disturbances is carried out,and a simplified scheme of the attitudemotion model of the spacecraft and the effects of different disturbances on the momentum moment and the rotational kinetic energy are given for a specific case.
