Sažetak

Japan decided to set up their satellite communication and positioning system, called "Quasi-Zenith Satellite System" (abbreviated QZSS) or in Japanese "Jun-Ten-Cho". In order to get QZSS satellite on the horizon above the elevation angle of 70° for ten hours, apparent orbits of 24-hour satellites in circular and elliptical trajectories have been tested. Thereby three QZSS satellites have been scheduled for alternate substitution during zenith in Japan. Position determining by GPS and QZSS satellites will be enhanced in the cities where the horizons are screened by high buildings. Besides, QZSS satellites will help mobile communications and broad casting without repeaters on the Earth surface or other electronic devices.
