摘要
PROBLEM TO BE SOLVED: To effectively utilize frequencies by providing a means by which a geosynchronous orbit satellite communication system and a non- geosynchronous orbit satellite communication system use the same frequency band in common. SOLUTION: A directivity of a radiation beam is set to a direction shifted from a point beneath a non-geosynchronous orbit satellite Li by a shift angle so as to part the radiation beam from a line segment tying the non- geosynchronous orbit satellite Li and a geosynchronous orbit satellite G by a prescribed angle or over. Thus, the directivity of the beam from the non- geosynchronous orbit satellite Lo is selected so that not a non-geosynchronous orbit satellite Li+1 but the non-geosynchronous orbit satellite Li covers a radiation area AtI+1, Thus, the interference between the radiation beam by the geosynchronous orbit satellite G and that of the non-geosynchronous orbit satellite Li is reduced and the geosynchronous orbit satellite communication system and the non-geosynchronous orbit satellite communication system can use a same frequency band in common.
