交会对接光学成像敏感器中合作目标的分析与设计

交会对接技术是实现太空梭、太空平台和空间运输系统的装配、回收、补给、维修、太空人交换及营救等在轨服务的先决条件，交会对接光学成像敏感器是两航天器交会对接近距离平移靠拢段唯一能够提供六自由度相对导航信息的敏感器，由安装于追踪飞行器上的相机和安装于目标飞行器上的合作目标组成，采用角反射器作为合作目标标志，完成两飞行器间的相对位姿的解算.对其需求分析、设计方案、回光能量测试等进行了讨论，该方案已在神舟十一号载人飞船、天舟一号货运飞船与天宫二号的交会对接任务中成功验证，后续针对空间站及光学舱任务进行适应性修改.

Analysis and Design of Cooperative Targets for Camera TypeRendezvous and Docking Sensor

Space rendezvous and docking technology is a prerequisite for on orbit services such as assembly, recovery, resupply, maintenance, and crew exchange or rescue of space shuttles, space platforms, and space transportation systems. Camera type rendezvous and docking sensor (CRDS) is the only sensor which can indicate six degree of freedom (6DOF) information about relative position and attitude between two vehicles over the final approach phase. And it is comprised of the camera mounted on the tracking aircraft and cooperative target clusters on the target aircraft. The relative position and attitude information can be obtained, adopting the corner reflectors as cooperative targets. Requirements analysis, design analysis, and the results of sensor performance testing with the targets are discussed in detail. The design was successfully applied in autonomous rendezvous and docking missions of SZ 11&TG 2 and TZ 1&TG 2. In the future, the design will be revised to better fit the missions such as KJZ and GXC.
