Positioning, Navigation, and Timing (PNT) Satellites
Japanese PNT Satellites (QZSS)
The complete constellation is planned to be in place by 2011, though no launches had been conducted by the end of 2009. Japan’s Quasi-Zenith Satellite System (QZSS) will consist of ## GEO satellites operating over Japan and surrounding areas. While these satellites are geosynchronous, orbiting the Earth once per day, they are not stationary as are FSS satellites. They are inclined-GEO satellites, meaning that they move in a north-south “figure eight” pattern as observed from a single point on the Earth.
