About this launch
Michibiki 7 (QZS-7) launched on a Mitsubishi Heavy Industries H3-22 from Yoshinobu Launch Complex LP-2, Tanegashima Space Center, Japan on August 10, 2026 at 19:23 UTC. The launch window ran from 19:23 to 20:23 UTC. It was Mitsubishi Heavy Industries's 58th launch, 2nd this year and humanity's 7,362nd orbital launch attempt. It was the 7th H3-22 flight and the 1st this year. The payload was bound for Geostationary Transfer Orbit (GTO). It reached a 398 × 35,382 km orbit inclined 22.9°.
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. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a three-spacecraft constellation in inclined, elliptical geosynchronous orbits.
