空间在轨装配技术综述

The construction demands for large space platforms and infrastructures such as space stations, space telescopes, large communication antennas, space solar power stations, in-orbit supply stations, deep space exploration stations and extraterrestrial bases, which represent national scientific and technological capability, are constantly increasing. The autonomous construction of these projects in space remains a huge challenging task. Since large space infrastructures play a significant role in future space exploration missions, various investigations have been performed by different space agencies to cope with this issue. This paper presents an overview of in-space assembly studies, systematically summarizing the research status and technological development of in-orbit assembly. The technological progress of manned and unmanned in-orbit assembly is first analyzed, and the development roadmap, assembly levels and methods of in-orbit assembly technology summarized. On this basis, the technical requirements for and application prospects of in-orbit assembly are sorted out, and the key enabling technologies of in-orbit assembly-the modular technology, robotic technology and ground simulation assembly technology are concluded, which are expected to provide useful reference for the future research of space in-orbit assembly.
