All-Phase Autonomous Quick Rendezvous and Docking Technology and In-Orbit Verification of Tianzhou-2 Cargo Spacecraft

介绍天舟二号货运飞船全相位自主快速交会对接技术和在轨飞行结果.介绍21世纪以来交会对接发展的两个趋势:自主和快速;给出天舟二号货运飞船全相位自主快速交会对接方案,以及主要技术特点;给出天舟二号货运飞船5~8 h飞控实施方案和推迟一天发射的飞控实施方案,以及在轨执行效果.天舟二号货运飞船入轨自主快速交会对接是世界上首次进行的全自主快速交会对接任务,为我国空间站工程后续任务奠定了坚实的技术基础.

This paper introduces the all-phase autonomous quick rendezvous and docking technology and in-orbit verification of Tianzhou-2 cargo spacecraft in China.First,two trends of rendezvous and docking development since the 21^(st) century are introduced:autonomous and quick.Then,the all-phase autonomous quick rendezvous and docking scheme of Tianzhou-2 cargo spacecraft and its main technical characteristics are given.Finally,the implementation plan of 5~8 h flight control of Tianzhou-2 cargo spacecraft and the implementation plan of flight control of one day delayed launch are presented,as well as the in-orbit verification effect.The autonomous quick rendezvous and docking of Tianzhou-2 cargo spacecraft in-orbit is the first fully autonomous quick rendezvous mission in the world,which laid a solid technological foundation for the Chinese space station project.
