DEPARTMENT DETAILS
Time and Frequency Department
Research in the Time and Frequency Department is focused on
ultra-sensitive short-term frequency stability measurement at low radio
frequency in ambient temperature, both in time and frequency
(spectral) domains. Research also concerns applications
of the dual-mixer time-difference multiplication method in accurate
measurement of short time-delays in electronic components.
Also investigated are methods for precise time-interval measurement and
accurate time transfer via satellite positioning systems and via optical
links. Part of the Department is Laboratory of the National Time and
Frequency Standard which ensures, within the National Metrology System,
the physical realization of the TAI second and UTC time scale. The
Laboratory also performs high-accuracy calibrations of industrial atomic
frequency sources, ultra-stable quartz oscillators, and GPS-disciplined
frequency sources and clocks.
