QZS 1 (Michibiki)

NSSDCA/COSPAR ID: 2010-045A

Description

QZS 1, a Japanese navigation satellite also known as Michibiki, was launched on 11 September 2010 from Tanegashima at 11:17 UT. The craft weighed 4100 kg and was launched by an H-2A rocket. QZS 1 is a JAXA satellite and is part of the QZSS (Quazi-Zenith Satellite System) that is aimed at overcoming ground interference by launching more navigation satellites strategically positioned high in the sky above Asia. The QZSS consists of a constellation of three spacecraft. QZS 1 Michibiki is phase 1 of the QZSS project. Michibiki is demonstrating the system's navigation instruments and proving the satellite works before Japan commits to launching the other two spacecraft. Michibiki will circle the Earth at a 45° inclination to the equator and will eventually park more than 20,000 miles above Earth. The satellite has a design life of 10 years.
