Abstract: Time frequency transfer technology has important application in positioning and navigation, high-speed communication, basic physics, national defense industry and other fields. In order to enable interdisciplinary researchers to quickly understand the research status in the field of time frequency transfer, review work of time frequency transfer technology is carried out. Firstly, the common methods and basic principles of time frequency transfer technology are systematically introduced, and the main characteristics, application background and research status of each technical scheme are analyzed; Then, by comparing the technical indicators, inherent characteristics and application scenarios of each technical system, this paper summarizes the main research problems and development trend of each transfer system, so as to provide technical support for the work in related fields.

Keywords: time frequency transfer; time synchronization; GNSS; optical fiber; optical bidirectional comparison
