Abstract

Time and frequency transfer is of great value in satellite navigation, communication and others fields. The existing link of time and frequency transfer based on laser pulse is mainly used for time transfer, it is unable to achieve the optical frequency transfer. In this paper, a method of satellite-ground time and frequency transfer based on ultra narrow linewidth laser and optical frequency comb is proposed. This method not only can implement the time transfer but also can implement the frequency transfer, which has the very high application value.
