Embodiment Construction
[0037] A time-frequency transmission system integrated with communication for symmetrical transceiving and bidirectional processing between satellites, such as figure 1 As shown, the technical system of symmetrical transceiver processing is adopted. By multiplexing the laser terminal with the laser communication system, the laser communication signal is used for time transmission, and the laser carrier signal is used for frequency transmission, which can be multiplexed with the existing laser communication unit. Realizing the deep integration of high-precision time-frequency transmission and communication has the prospect of space engineering application in the next generation satellite navigation system, and has the potential of extensive space applications.
[0038] The time-frequency transfer system mainly includes an optical comb frequency synthesis unit, an inter-satellite laser communication terminal, and an inter-satellite time-frequency transfer processing unit, among w...
