Currently, to obtain the correct frequency, rubidium atomic oscillators and cesium atomic oscillators are used. Rubidium atomic oscillators have high short-term stability, but their long-term stability deteriorates due to aging, resulting in a decrease in accuracy. In this study, we achieved high accuracy and stability of the rubidium atomic oscillator by synchronizing it with the 1PPS of GPS using a phase-locked loop circuit set to the optimal characteristic frequency. In addition, we added a function to detect spoofing attacks in the circuit for safety. Furthermore, we measured the DTTB frequency. |
