Absolute frequency of at uncertainty by reference to remote Primary Frequency Standards
Nils Nemitz, Tadahiro Gotoh, Fumimaru Nakagawa +4
The optical lattice clock NICT-Sr1 regularly reports calibration measurements of the international timescale TAI. By comparing measurement results to the reports of eight Primary F…
Months-long real-time generation of a time scale based on an optical clock
Hidekazu Hachisu, Fumimaru Nakagawa, Yuko Hanado +1
Time scales consistently provide precise time stamps and time intervals by combining atomic frequency standards with a reliable local oscillator. Optical frequency standards, howev…
SI-traceable measurement of an optical frequency at low level without a local primary standard
Hidekazu Hachisu, Gérard Petit, Fumimaru Nakagawa +2
SI-traceable measurements of optical frequencies using International Atomic Time (TAI) do not require a local primary frequency reference, but suffer from an uncertainty in tracing…
