Методы сличения удалённых шкал времени, применяемые в работе Государственного первичного эталона единиц времени, частоты и национальной шкалы времени ГЭТ 1-2022, не обеспечивают выполнение перспективных требований к синхронности UTC(SU) и UTC. В настоящее время не производится прогнозирование расхождения UTC(SU) и UTC, на практике используют данные официальных бюллетеней Международного бюро мер и весов. Эти данные доступны с большой задержкой во времени, что усложняет обеспечение синхронности национальной шкалы времени с международной. В настоящем исследовании разработаны методы и алгоритмы, которые позволят обеспечить выполнение перспективных требований к пределам допустимого расхождения UTC(SU) и UTC. Решены следующие задачи: выбран метод сличения удалённых шкал времени, разработан алгоритм оперативного автоматического прогнозирования расхождения названных выше шкал времени с задержкой не более одних суток на основе выбранного метода сличения. Разработано программное обеспечение, реализующее предложенные методы и алгоритмы. Проведён анализ эффективности работы разработанной системы на основе сравнения с оценками Международного бюро мер и весов. Область применения полученных результатов – обеспечение функционирования ГЭТ 1-2022 в рамках заданных технических требований.</p></abstract><trans-abstract xml:lang="en"><p>The problem of maintaining synchronization of the national time scale of the Russian Federation UTC(SU) with the international coordinated time scale UTC within the specified limits is considered. Methods for comparing remote time scales currently used in the work of the State Standard of Time and Frequency GET 1-2022 do not allow meeting the upcoming requirements for UTC(SU) and UTC synchronization. Forecasting the difference between UTC(SU) and UTC is currently not carried out; in practice, data from the official bulletins of the International Bureau of Weights and Measures (BIPM) are used. These data are available with a large time delay, which also makes it difficult to ensure that the national time scale is in sync with the international one. The purpose of this study is to develop methods and algorithms that will ensure the fulfillment of upcoming requirements for the limits of acceptable difference between UTC(SU) and UTC. To do this, it is necessary to solve the following tasks: the choice of a method for comparing remote time scales, the development of an algorithm for the operational automatic prediction of the discrepancy of the above time scales with a delay of no more than one day based on the chosen method of comparison. To accomplish the tasks set, software was developed that implements the proposed methods and algorithms. An analysis of the effectiveness of the developed system was also carried out based on a comparison with the estimates of the International Bureau of Weights and Measures. The scope of the results obtained is to ensure the functioning of the State Standard GET 1-2022 within the framework of the technical requirements specified for it.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сличение эталонов времени</kwd><kwd>глобальные навигационные спутниковые системы</kwd><kwd>фазовые измерения</kwd><kwd>прогнозирование шкал времени</kwd></kwd-group><kwd-group xml:lang="en"><kwd>remote timescales comparison</kwd><kwd>GNSS</kwd><kwd>phase measurements</kwd><kwd>timescale prediction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">.
