Description

technical field [0001] The invention relates to a time-frequency transfer system integrated with communication for bi-directional processing of inter-satellite symmetric sending and receiving, and belongs to the field of time-frequency transfer. Background technique [0002] The transmission of high-precision time and frequency is a necessary condition for the establishment and maintenance of coordinated universal time UTC, and it is also an essential technology for the establishment and maintenance of GNSS system time and high-precision time synchronization between system nodes. At the same time, with the development of optical time-frequency technology, the accuracy of atomic clocks has been continuously improved. The stability of the latest laboratory high-precision optical clocks has reached the E-18 level. The definition of the next generation of seconds is also based on the definition of optical clocks. Time-frequency transmission and comparison accuracy put forward hi...
