Summary
Michibiki 4 (QZS-4) launched on a Mitsubishi Heavy Industries H-IIA 202 from Yoshinobu Launch Complex LP-1, Tanegashima Space Center, Japan on October 9, 2017. It was Mitsubishi Heavy Industries's 35th launch, 5th this year and humanity's 5,681st orbital launch attempt. It was the 22nd H-IIA 202 flight and the 3rd this year. The payload was bound for Geosynchronous Transfer Orbit (GSTO). Michibiki-4, one of 2 catalogued objects, reached a 352 × 35,367 km orbit inclined 31.7°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
The Quasi-Zenith Satellite System (QZSS) is a three-satellite regional time transfer system and the satellite-based augmentation system for the GPS that would be receivable within Japan. The primary purpose of QZSS is to increase the availability of GPS in Japan's numerous urban canyons, where only satellites at very high elevation can be seen. A secondary function is performance enhancement, increasing the accuracy and reliability of GPS derived navigation solutions. A single satellite weighs about 4000 kg, has an expected lifetime of 15 years and is put in a elliptical, highly inclined geosynchronous orbit.
