The report presents the results of maintaining the national time scale of Ukraine, UTC (UA), using the prediction recursive lattice filters that indicate high effectiveness results of the proposed algorithms for internal comparisons. Analysis of the data shows that the use of lattice filters allows to keep the national time scale within ± 10 ns, that is comparable with the time scales of countries, which have about ten and more hydrogen and cesium standards as well as cesium fountains and generators on cold strontium atoms as part of their primary measurement standards of time and frequency. In the future, the results will be used by the Service of Universal Time and Reference Frequencies of Ukraine.
