Mission

Michibiki 7 (QZS-7) on H3-22 from Yoshinobu Launch Complex LP-2. Launch time, status and recorded date changes from Launch Library 2.

QZSS (Quasi Zenith Satellite System) is a Japanese satellite navigation system operating from inclined, elliptical geosynchronous orbits to achieve optimal high-elevation visibility in urban canyons and mountainous areas. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation.
