Repetitive locking technology is a key technology on spacecraft for achieving repeated locking and separation between the detachable structure of the aircraft and the fixed structure. This paper gives an overview of the repeated locking techniques used by different countries in space vehicles, spacecraft and satellites. It elaborates on the research progress of mechanical locking, memory alloy locking and electromagnetic locking technology. Furthermore the advantages and disadvantages of the locking scheme, the development trend and prospect of different repetitive locking technologies in future applications are prospected, which provide a reference for the selection and development of spatial repetitive locking technology.
