Полученные оценки средних уровней электромагнитного фона, соответствующие диапазону реальных значений средней плотности беспроводного трафика, создаваемого созвездиями НСС на земной поверхности, существенно превышают уровни естественного электромагнитного фона. Это соответствует оценкам, полученным ранее с использованием данных о полной излучаемой мощности НСС и их количестве в мегасозвездии, и подтверждает адекватность представленной методики. </p></abstract><trans-abstract xml:lang="en"><p>The paper presents a technique for analyzing the characteristics of the electromagnetic background near the earth’s surface generated by emissions from megaconstellations of low-orbit communication satellites (LOCSS) based on estimates of the average territorial density of wireless traffic generated by them on the earth’s surface and available system characteristics of the LOCSS and their constellations, such as orbit altitude, characteristics of antenna patterns, limitations on the angle at which the main lobe of the LOCSS antenna can be directed to the earth’s surface, and features of subscriber terminal servicing scenarios. The obtained estimates of the average levels of the electromagnetic background, corresponding to the range of real values of the average density of wireless traffic generated by LOCSS constellations on the earth’s surface, significantly exceed the levels of the natural electromagnetic background. This is consistent with the estimates obtained earlier using data on the total radiated power of LOCSS and their number in the megaconstellation, and confirms the adequacy of the presented technique.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>низкоорбитальный спутник</kwd><kwd>группировка</kwd><kwd>электромагнитное излучение</kwd><kwd>диаграмма направленности антенны</kwd><kwd>территориальная плотность трафика</kwd><kwd>электромагнитный фон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>low-earth orbit satellite</kwd><kwd>constellation</kwd><kwd>electromagnetic radiation</kwd><kwd>antenna pattern</kwd><kwd>area traffic capacity</kwd><kwd>electromagnetic background.</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">Mordachev V., Tsyanenka D., Svistunou A.
