Abstract
A communication line not affected by artificial structures and plants is established between mobile objects and stationary stations surrounded with skyscrapers, and economical artificial satellite service capable of efficiently performing satellite broadcast, mobile satellite communication, satellite-to-satellite communication and earth surveillance is provided using the communication line and by constructing the system with a small number of satellites.Six orbital elements 7-12 of a plurality of artificial satellites at reference time 5 are determined, and a plurality of elliptical orbits corresponding to the determined six orbital elements are combined, and then each of the satellites is appropriately arranged on each of the orbits to form a group of artificial satellites. Satellite communication or satellite broadcast is performed using the group of artificial satellites.
