Research on Disciplined Rubidium Clock Technology Based on the Beidou-3 New System Signal Common View Technology

The technology of disciplined rubidium clock based on common view time comparison is simple in principle and easy to implement. It is widely used in the establishment of time-frequency synchronization network in electric power, communication and other fields. This method can realize high precision time reproduction of slave station to master station standard time, and ensure the time unity of time-frequency synchronization network. Compared with Beidou-3 new system signal, the signal bandwidth of Beidou-3 new system is wider, the anti-interference ability is enhanced, and the impact of multi-path error noise is small. In this paper, the technology of disciplined rubidium clock based on Beidou-3 new system signal common view is proposed, the time difference of Beidou-3 new system signal B1C and B2a dual-frequency combination common view time comparison is used to discipline the rubidium clock. The test results show that, the technology of disciplined rubidium clock based on the new system signal common view compared to disciplined rubidium clock based on Beidou-2 common view, the rubidium output frequency relative frequency deviation of the rubidium clock increases by more than 30%, the standard deviation of the common view clock difference increases by more than 40%, and the frequency stability increases by more than 50%.
