AI Technical Summary
Centralized time and frequency references have poor security. Environmental changes can cause related changes in the characteristics of atomic clocks, leading to systematic deviations in the time and frequency references. Furthermore, existing technologies cannot improve the distributed use capability of atomic clock groups without sacrificing timekeeping accuracy.
The distributed timekeeping atomic clock group method using fiber optic bidirectional comparison is adopted. By deploying atomic clock groups in a distributed manner, the time and frequency of the optical fiber are compared remotely, the clock difference information is calculated, and the phase adjustment and frequency fine-tuning are performed to achieve time and frequency synchronization of each node and improve timekeeping performance.
Without sacrificing timekeeping accuracy, it enhances the distributed utilization and resilience of atomic clock arrays, improves operational safety and the continuity of time and frequency signal output, reduces environmental impact, and offers good economic benefits and high safety.
