Abstract:	The Quasi-Zenith Satellite System (QZSS), a Japanese satellite navigation system, broadcasts GPS-interoperable signals and augmentation signals as well as original Japanese signals from an inclined elliptical geosynchronous orbit. Using this system, users around Japan and Oceania can make use of seamless positioning, navigation, and timing services, even in urban canyons and mountainous areas [1]. The first satellite of the Quasi-Zenith Satellite System, MICHIBIKI, was successfully launched on September 11, 2010, by a Japanese H2A launch vehicle is operating successfully. In-Orbit Checkout was conducted by the government sector, consisting of four ministries, National Institute of Information and Communications Technology, (NICT), National Institute of Advanced Industrial Science and Technology (AIST), Geospatial Information Authority of Japan (GSI), Electronic Navigation Research Institute (ENRI), and JAXA (Japan Aerospace Exploration Agency), and was completed successfully. From the middle of December 2010, JAXA changed the navigation signals to the standard code. The technical verification and the application demonstration were also conducted and successfully finished in June 2011, [2]. NEC Corporation is responsible for the total system, QZSS, the ground system, and the on-board payload, QZS Navigation Payload (NP). In this paper, the in-orbit performance of the navigation performance of QZSS and L-Band Navigation Payload of QZS-1 are described.
