Для анализа электромагнитной совместимости низкоорбитальных группировок спутниковой связи (НГСС) с наземными радиосистемами проведена оценка плотности потока мощности радиочастотного электромагнитного излучения, создаваемого НГСС у поверхности Земли. Оценка основана на анализе системных характеристик НГСС, параметров космических аппаратов и земного сегмента (абонентских терминалов, шлюзовых станций). Проанализированы условия, при которых излучение космических аппаратов может приводить к помехам функционирования наземных фиксированных служб связи, в том числе радиорелейных линий связи, использующих те же частоты на вторичной основе. Установлено, что при увеличении количества космических аппаратов и шлюзовых станций в одной НГСС вероятность создания помех функционированию радиорелейной линии со стороны этой НГСС уменьшается из-за увеличения минимального угла места обслуживания абонентских терминалов. Однако увеличение количества развернутых НГСС требует ужесточения требований к функционированию каждой из них для предотвращения помех.

To analyze the electromagnetic compatibility of low-orbit satellite constellations оf communication (LOSCC) with ground-based radio systems, the power flux density of radio-frequency electromagnetic radiation generated by LOSCC near the Earth’s surface was estimated. The estimate is based on the analysis of LOSCC system characteristics, spacecraft and ground segment (subscriber terminals, gateway stations) parameters. The conditions under which spacecraft radiation can cause interference with the functioning of terrestrial fixed communication services, including radio relay communication lines, using the same frequencies on a secondary basis were analyzed. It was found that with an increase in the number of spacecraft and gateway stations in the LOSCC, the probability of interference with the functioning of the radio relay line from this LOSCC decreases due to an inc rease in the minimum elevation angle of subscriber terminals. However, an increase in the number of deployed LOSCCs requires stricter requirements for the functioning of each of them to prevent interference.
