| Outline |
QZSS is a constellation of Japan's positioning satellites which will have geosynchronous orbit with inclination of 45 degrees in order to pass near the zenith over Japan, thus providing seamless service irrespective of geographical features. They will significantly improve the accuracy of positioning in areas where signals from GPS Satellites are not fully received due to skyscrapers or canyons. 3 QZS' are needed in order to make sure at least one QZS is at zenith over Japan. |
