The invention discloses a collision early warning method for a spacecraft. The method relates to the field of spacecraft collision early warning, and comprises the following steps: obtaining first orbit data of a spacecraft and second orbit data of a plurality of space targets; performing epoch and perigee-apogee height screening on the plurality of space targets based on the first orbit data and the second orbit data to obtain candidate space targets; searching a target time interval with a potential rendezvous risk based on the first orbit data and second orbit data of the candidate space target; and determining a relative distance minimum value between the spacecraft and the candidate space target in the target time interval, and determining a collision early warning result between the spacecraft and the candidate space target based on the relative distance minimum value. The method can reduce the calculation amount of collision early warning and improve the calculation efficiency of spacecraft collision early warning under the condition of ensuring no missed alarm.

    本发明公开了一种航天器的碰撞预警方法。其中,该方法涉及航天器碰撞预警领域,包括:获取航天器的第一轨道数据和多个空间目标的第二轨道数据;基于第一轨道数据和第二轨道数据对多个空间目标进行历元和近地点—远地点高度筛选,得到候选空间目标;基于第一轨道数据和候选空间目标的第二轨道数据,搜索存在潜在交会风险的目标时间区间;在目标时间区间内确定航天器与候选空间目标的相对距离极小值,并基于相对距离极小值,确定航天器与候选空间目标的碰撞预警结果。本发明能在保证不漏警的情况下,减少碰撞预警的计算量,提高航天器碰撞预警的计算效率。
