подтверждена  эффективность  разработанных  алгоритмов  в  условиях  сильных  геомагнитных возмущений. 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
