Photonic Services for Time and Frequency Transmission in the Czech Republic
Original language description
In every country exists a time and frequency laboratory that operates a certain set of atomic clocks with goal to provide national approximation of UTC time scale. Generally, higher number of these interconnected clocks (Caesium primary standards and Hydrogen masers) might improve accuracy and stability of the time scale. The term "interconnection" in this context means that we have to transfer time between them despite of their location at geographically distant places - the common method is a dedicated two-way satellite link or a GPS based system, however utilization of fibre links constantly increases. And present all-optical networks allow stable transmission of information. However to increase stability specific measures are necessary. Contribution summarizes the reasons for building of infrastructure dedicated to transfer of accurate time and frequency in the Czech Republic. It shows achieved results and indicated necessary steps for further stability improvements.
