Предложена модификация разработанной ранее первым из авторов стратегии детектирования выбросов во временных рядах зашумлённых данных, содержащих неизвестный тренд. Ранее разработанная стратегия состоит из двух этапов: построения тренда и применения к остаткам, полученным после вычитания найденного тренда из данных измерений, алгоритма поиска оптимального решения. Поиск тренда осуществляется в классе степенных полиномов с помощью метода наименьших квадратов по наборам опорных значений, количество которых задаётся заранее. Алгоритм поиска тренда осуществляется с помощью абсолютно сходящегося итерационного процесса и основан на методе минимизирующих последовательностей (наборов). При реализации ранее разработанной стратегии необходимо задать общее количество опорных значений, по которым строится тренд, что может исказить определение тренда и детектирование выбросов. В предложенной стратегии исправлен указанный недостаток: число опорных значений выбирается из условия минимизации количества обнаруженных выбросов с одной стороны, и из условия максимизации числа опорных значений – с другой. Приведены результаты численного тестирования на реальных данных для спутниковых лазерных дальномерных измерений. Разработанную стратегию можно применять для обнаружения и устранения выбросов из временных рядов измерительных данных на стадии их предварительной обработки.</p></abstract><trans-abstract xml:lang="en"><p>One of the problems related to detection of coarse measurements (outliers) in automated processing of data series measured in technical devices has been considered. A modifi cation of the strategy developed by the fi rst author for detecting outliers in time series of noisy data containing an unknown trend is proposed. The previously developed strategy consists of two steps: fi nding a trend and applying to the residues obtained after subtracting the found trend from the measurement data, an algorithm for fi nding the optimal solution. The search for a trend is carried out in the power polynomials class by means of the least squares method using sets with preset number of reference values. The trend search algorithm is carried out using a completely convergent iterative process and is based on the method of minimizing sequences (sets). The disadvantage of this strategy is the need to set a priori the total number of reference values by which the trend is built, which can lead to a distorted determination of the trend and incorrect detection of outliers. In the proposed strategy, the number of reference values is selected from the condition of minimizing the number of detected outliers on the one hand, and from the condition of maximizing the numberof reference values on the other. The results of numerical testing on real data for satellite laser range fi nding measurements are given. The proposed strategy can be used to detect and eliminate outliers from time series of data at the stage of their preliminary processing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>временные ряды</kwd><kwd>предварительная обработка данных</kwd><kwd>выбросы</kwd><kwd>чистка данных от выбросов</kwd><kwd>оптимальное решение</kwd><kwd>минимизирующие наборы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>time series</kwd><kwd>data preprocessing</kwd><kwd>outliers</kwd><kwd>data cleaning</kwd><kwd>optimal solution</kwd><kwd>minimizing sets</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">International GNSS Service, available at: http://www.igs.org/network (accessed: 05.04.2022).</mixed-citation><mixed-citation xml:lang="en">International GNSS Service, available at: http://www.igs.org/network (accessed: 05.04.2022).</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Пасынок С.
