quasi zenith satellite system

QZSS - Navipedia

This gives rise to the term "quasi-zenith" for which the system is named. The design life of the quasi-zenith satellites is of 10 years. The first satellite Michibiki (QZS-1) was launched on 11 September 2010 and injected into the Quasi-Zenith Orbit on 27 September.


Overview of the Quasi-Zenith Satellite System (QZSS ...

QZSS is a Japanese satellite positioning system composed mainly of satellites in quasi-zenith orbits (QZO). However, the term "Quasi-Zenith Satellite (QZS)" can refer to both satellites in QZO and geostationary orbits (GEO). For that reason, the name "QZO satellite" is used when it is necessary to specifically refer to satellites in QZO.
