| 对完成任务的运载火箭末级、失效卫星等空间非合作目标进行空间操作是复杂的，需要地面测控网与主动航天器的密切合作才能完成抵近及相应操作。以火箭末级残骸作为空间非合作目标，给出了远程自主接近的轨道设计方法。通过地面遥控上传的目标轨道参数，主动航天器进行自主异面机动、主动调相等多次点火，完成对非合作目标的远程接近，接近距离在50km之内，2016年6月底远征一号甲上面级的成功飞行验证了该方法和设计结果的有效性。 |

| Abstract: |
| Non-cooperation space target, such as the final debris of the launch vehicle or disabled satellite, is key target of space operate. The mission is complex and very interesting, which needs the chase vehicle cooperating with ground measurement and control network to approach and operate. Orbit design method of long range approach with noncooperation space target is described in this paper. The target here is the final stage of the launch vehicle which has completed its mission. The spacecraft performs selfcontrol based on the orbit elements uploaded by the remote control. Nonplanar maneuvering and phase maneuvering give rise to multiple burns. Thereafter, the chase vehicle approaches the target vehicle, and the minimum distance is less than 50km. The flight of Yuan-Zheng-1A upper stage has tested the method at the end of June, 2016. |
