Quasi-zenith Satellite System (QZSS) is a constellation of Japan′s geographic positioning satellites that significantly improve the accuracy of positioning
in areas where GPS signals are not fully received due to interference caused by skyscrapers and mountainous terrain. The H-IIA Launch Vehicle No. 35 frame configuration
is a H2A204 launch vehicle utilizing four SRB-As, because QZS-3 has a launch mass of 4,700 kilograms, around 700 kilograms more than QZS-2.
Mitsubishi Heavy Industries, Ltd. and JAXA successfully launched H-IIA Launch Vehicle No. 35 (H-IIA F35) which encapsulates Michibiki No. 3, (Quasi-Zenith
Satellite System; geostationary orbit) at 2:29:00 p.m. on August 19, 2017 (JST) from JAXA's Tanegashima Space Center.
The launch and flight of H-IIA Launch Vehicle No. 35 proceeded as planned and the separation of the satellite was confirmed at approximately 28 minutes and 37 seconds after liftoff.
