Japan Launches First GPS Satellite (Quasi-Zenith Satellite System "MICHIBIKI")

Japan is ready to implement its version of the sky spy to track, trace and database. The goal of the Quasi-Zenith Satellite "MICHIBIKI" (QZSS) is to deploy three satellites in orbit so as to always have one flying near the zenith over Japan. By doing so, the system can provide a highly accurate satellite positioning service covering close to 100% of Japan even in urban canyons and mountainous areas.

Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency (JAXA) launched the first Quasi-Zenith Satellite System "MICHIBIKI" by the H-IIA Launch Vehicle No. 18 (H-IIA F18) at 8:17:00 p.m. on September 11, 2010 (Japan Standard Time, JST) from the Tanegashima Space Center.

The launch vehicle flew smoothly, and, at about 28 minutes and 27 seconds after liftoff, the separation of the MICHIBIKI was confirmed.

We would like to express our profound appreciation for the cooperation and support of all related personnel and organizations that helped contribute to the successful launch of the H-IIA F18.

At the time of the launch, the weather was fine, a wind speed was 3.7 meters/second from the west-south-west and the temperature was 26.0 degrees Celsius.
