Определение концентрации электронов в ионосфере над территорией Республики Беларусь по данным глобальных навигационных спутниковых систем

Приводятся результаты экспериментальных исследований концентрации электронов в ионосфере над территорией Республики Беларусь по данным глобальной навигационной спутниковой системы. 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.
