Abstract
An information providing method and apparatus in which a radio wave signal is transmitted from plural artificial satellites and received at plural receiving equipment located within a pre-defined service area, and receiving within a pre-defined range of operational elevation angle by a receiving antenna. The plural artificial satellites are viewable in turn within a pre-defined range of operational elevation angle at an arbitrary location within the pre-defined service area, and an orbit is arranged so that at least one artificial satellite is viewable. Each orbit of the plural artificial satellites is arranged on an individual orbital plane according to a designated service hour. The individual orbit is located in a range where an orbital inclination angle is 63.4 degrees or closer to Japan, and a right ascension of a north-bound node of the individual artificial satellite is separated approximately at regular intervals.
