PROJECT TITLE :
The dynamic Allan Variance IV: characterization of atomic clock anomalies
The amount of applications where precise clocks play a key role is steadily increasing, satellite navigation being the most example. Precise clock anomalies are hence essential events, and their characterization could be a elementary downside. When an anomaly happens, the clock stability changes with time, and this variation can be characterized with the dynamic Allan variance (DAVAR). We acquire the DAVAR for a series of common clock anomalies, specifically, a sinusoidal term, a part jump, a frequency jump, and a sudden modification in the clock noise variance. These anomalies are particularly common in house clocks. Our analytic results clarify how the clock stability changes during these anomalies.
