Abstract

Настоящее изобретение относится к системе спутниковой связи, включающей в себя мобильный пользовательский терминал. Для создания системы спутниковой связи, обеспечивающей в любой заданной области земной поверхности связь с мобильным пользовательским терминалом через обычные спутники связи, на наклоненной орбите эксплуатируют квази-геостационарный спутник, передающий сигнал s'(t) нисходящей линии связи с расширенным спектром в заданную область земной поверхности, который принимается и сжимается по спектру мобильным пользовательским терминалом.Международная заявка была опубликована вместе с отчетом о международном поиске.
