Приведены результаты анализа зависимости средних уровней электромагнитного фона у земной поверхности от количества спутников в группировке при различных сценариях реализации информационного обслуживания наземных абонентских терминалов, подтверждающие адекватность разработанной методики. Сделан вывод, что ожидаемые уровни электромагнитного фона диапазона СВЧ, создаваемого мегасозвездиями низкоорбитальных спутников связи, на много порядков превышают уровни электромагнитного фона естественного происхождения, что существенно меняет физические характеристики среды обитания.</p></abstract><trans-abstract xml:lang="en"><p>A technique has been proposed for predicting the average intensity of electromagnetic background created near the Earth’s surface by a constellation of communication satellites, taking into account the number of satellites in the constellation, the satellite total radiated power, parameters of its radiation in the main and side lobes, the orbit altitude and restrictions on the tilt angle of service of ground-based equipment. The results of the analysis of the dependence of the average electromagnetic background levels at the Earth’s surface on the number of satellites in the constellation under various scenarios for the implementation of information services for terrestrial subscriber terminals are presented, conﬁrming the adequacy of the developed approach. It is concluded that the expected levels of electromagnetic background in the microwave range created by megaconstellations of low-orbit communication satellites are many orders of magnitude higher than the levels of electromagnetic background of natural origin, which signiﬁcantly changes the physical characteristics of the habitat.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>низкоорбитальный спутник связи</kwd><kwd>группировка</kwd><kwd>электромагнитное излучение</kwd><kwd>полная излучаемая мощность</kwd><kwd>главный лепесток</kwd><kwd>боковые лепестки</kwd><kwd>электромагнитный фон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-earth orbit communication satellite</kwd><kwd>constellation</kwd><kwd>electromagnetic radiation</kwd><kwd>total radiated power</kwd><kwd>main lobe</kwd><kwd>side lobes</kwd><kwd>electromagnetic background</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках научного проекта № 23-3172 при финансовой поддержке Министерства образования Республики Беларусь.</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of scientific project No 23-3172 with the financial support of the Ministry of Education of the Republic of Belarus.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Martel J.
