Key Points

The optically steered time scales achieved alignment with UTC(NPL) at the nanosecond level, improving precision.
This method utilizes advanced optical atomic clocks to enhance the frequency steering of hydrogen masers.
Aligning these time scales with UTC demonstrates the effectiveness of optical atomic clocks in timekeeping.
Improvements at the sub-nanosecond level signify notable advancements in time scale generation.

Implication

Frequency steering aligns time scales with UTC(NPL) and UTC at nanosecond precision, indicating improved accuracy.

Abstract

We present the frequency steering of two continuously-running hydrogen masers using NPL’s state-of-the-art optical atomic clocks. The resulting optically steered time scales are aligned with UTC(NPL) and UTC at the nanosecond and sub-nanosecond level, respectively.
