摘要：

The Quasi Zenith Satellite System, a Japanese satellite navigation system, is under development. The system broadcasts GPS-interoperable and augmentation signals as well as original Japanese signals from an inclined, elliptical geosynchronous orbit. Using this system, users around Japan and Oceania can use seamless positioning, navigation, and timing services, even in urban canyons and mountainous areas. A government policy supports the project to promote the use of geographical spatial information linked to satellite-based navigation for a wealthy and secure life in accordance with the rapid increase of satellite navigation users nationwide. To support that policy, JAXA is in charge of developing the first stage of QZSS in collaboration with related ministries and national institutes. Attention is devoted to making the system reliable and economical using legacy Japanese GEO satellite system technologies, not only satellite technology, but also ground systems and operations technologies.
