Robust Optical Clocks for International Timescales
Annotation in Czech
The overall objective of this project is to bring European optical clocks to the stage where they regularly contribute to TAI via reporting to the International Bureau of Weights and Measures (BIPM). Specifically, the objectives are: 1. To improve the robustness of optical clocks and automate their operation, including tools for on-the-fly evaluation of systematic frequency shifts. The target is to achieve unattended uptimes of 80 %–90 % over a few weeks for both trapped ion and neutral atom lattice clocks. 2. To investigate the international consistency of optical clocks through a coordinated programme of frequency comparisons. This programme will include remote comparisons using both optical fibre links and GPS-based satellite techniques, providing for wide participation as well as the lowest possible fractional comparison uncertainties (below 1018). Optical frequency ratio measurements will enable consistency checks to be performed where no direct link between clocks exists. Traceability to the present definition of the SI second will be provided by absolute frequency measurements relative to caesium primary frequency standards.

Project results evaluation
Following the condition that the candidate of financial contribution was evaluated and afterwards selected by international provider in accordance with the rules of the program the Ministry of Education, Youth ans Sports does not realize the evaluation of project results. The project is evaluated only after its approval by an international provider.
