Head Soldatov Volodymyr V., Registration Date 22-01-2026 Organization National Science Center "Institute of Metrology" popup.description1 Ensuring the unity of time and frequency measurements in Ukraine and comparing the UTC(UA) scale with the UTC Universal Coordinated Time scale, preserving and operating the national reference base, the national (state primary) standard of time and frequency units (NDETU TF-01-2021), providing time-frequency information and information to ensure a unified accounting and reporting time of Ukraine popup.description2 The object of the study is the process of functioning and development of the Unified Time and Reference Frequencies Service (UTRS). The purpose of the work is to ensure the unity of time and frequency measurements in Ukraine, as well as to provide time-frequency information and information to ensure a unified accounting and reporting time. The subject of the study is the national (state primary) standard of time and frequency units NDETU TF-01-2021, the national time scale, methods of transmitting time and frequency units, new methods and means of measuring time and frequency. The research method is experimental: conducting measurements using the national (state primary) standard of time and frequency units and statistical analysis of the measurement results. The functioning of the structural unit of the NSC "Institute of Metrology" - the research laboratory "Main Center of the Unified Time and Reference Frequencies Service" (hereinafter referred to as the UTRS) is ensured. The functioning of the national (state primary) standard of time and frequency units, which is stored in the Central Radio Frequency Center, the reproduction and storage of time and frequency units by this standard, the maintenance of the national coordinated time scale of Ukraine (UTC(UA)) and its comparison with the International Coordinated Time Scale and national time scales of standards of other countries, as well as participation in the formation of the International Atomic Time Scale, has been ensured.
