В качестве входных данных использовались результаты измерений спутниковой системы точного позиционирования Республики Беларусь и навигационные данные высокоорбитальных навигационных спутников в формате RINEX. Приведены выражения для расчета полного электронного содержания при помощи двухчастотного метода и комбинации измерений по фазовым и кодовым задержкам. Решены задачи коррекции проскальзывания цикла навигационного сигнала и определения дифференциальных кодовых задержек. Продемонстрированы примеры вычисления вертикального электронного содержания над Республикой Беларусь в разные моменты времени. Полученные результаты целесообразно использовать при мониторинге ионосферы с целью обеспечения надежной работы радиосистем, обнаружения ионосферных аномалий естественного и искусственного происхождения, а также прогнозирования природных явлений на их основе.</p></abstract><trans-abstract xml:lang="en"><p>We present the results of experimental studies of electron content in the ionosphere over the territory of the Republic of Belarus based on data from global navigation satellite systems. The results of measurements of the precise positioning system of the Republic of Belarus and navigation data of GPS satellites in RINEX format were used as input data. Expressions for calculation of the total electron content using the two-frequency method and a combination of measurements by phase and code delays are given. Algorithms for eliminating cycle slip and determining differential code biases are used. Examples of calculating the vertical electron content over the Republic of Belarus at different moments of time are demonstrated. The obtained results are reasonable to use in monitoring of the ionosphere in order to provide reliable operation of radio systems, detection of ionospheric anomalies of natural and artificial origin, as well as forecasting of natural phenomena on their basis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ионосфера</kwd><kwd>радиотомография</kwd><kwd>полное электронное содержание</kwd><kwd>вертикальное электронное содержание</kwd><kwd>глобальная спутниковая навигационная система</kwd><kwd>навигационный сигнал</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ionosphere</kwd><kwd>radio tomography</kwd><kwd>total electron content</kwd><kwd>vertical electron content</kwd><kwd>global navigation satellite system</kwd><kwd>navigation signal</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">Hofmann-Wellenhof B., Lichtenegger H., Wasle E.
