摘　　要：随着高精度光钟及其各种应用的发展,人们对时频传输技术的精度要求越来越高。基于光纤的时频传输技术已经较为成熟,而自由空间激光时频传输技术可以应用在不方便铺设光纤、快速机动场合以及星地、星间时频传输领域。介绍了国内外在近地空间以及星地间进行时频传输的研究现状,并对其未来的发展趋势进行了展望。未来自由空间激光时频传输将会朝更高的传输精度、时频传输、测距、通信一体化以及时频空间组网的方向发展。With the development of high precision optical clock and its various applications,higher and higher precision is needed for time-frequency transmission technology.Time-frequency transmission technology based on optical fiber has been relatively mature,while the time-frequency transmission technology based on free-space laser can be applied to the fields of inconvenient laying of optical fiber,fast maneuvering,and time-frequency transmission between the satellite and the Earth and between satellites.This paper introduces the research status of near-earth space and time-frequency transmission between the satellite and the Earth,and the development trend is also prospected.In the future,free-space laser time-frequency transmission will develop towards higher transmission accuracy,time-frequency transmission,ranging,communication integration,and time-frequency space networking.
