空间的交会对接,是现代复杂航天器尤其是载人空间站在长期轨道运行期间不可缺少的操作活动,是实现空间装配、回收、补给和维修服务等高级空间操作的先决条件。两个飞行器在空间实现交会对接是一项十分复杂的高难度航天技术,涉及航天器轨道控制技术、航天器姿态控制技术,主要由航天器控制系统完成。航天器的空间交会对接技术,是指两个或两个以上的航天器,在预定的轨道位置和时间 The rendezvous and docking of space is an indispensable operational activity of modern complex spacecraft, especially manned space station during long-term orbit, and is a prerequisite for advanced space operations such as space assembly, recovery, replenishment and maintenance services. Spacecraft rendezvous and docking of two aircraft is a very complex and challenging aerospace technology involving spacecraft orbit control technology and spacecraft attitude control technology, which is mainly accomplished by the spacecraft control system. Spacecraft rendezvous and docking technology spacecraft, refers to two or more spacecraft, at a predetermined track position and time
