摘要

The Quasi-zenith Satellite System is a satellite navigation system in Japan which is designed to complement and augment global-positioning satellites (GPS). This paper investigated the impact of the integration of GPS and development of the QZSS system in the East Asian Region. QZSS satellite constellation and signal structure are briefly introduced, four QZSS satellite orbit options (8-shaped, Egg-shaped 1, Asymmetric 8-shaped, Egg-shaped 2) are introduced in this research. Performance analyses in the East Asian region when GPS with and without QZSS augmentation were obtained by triple-frequency simulator. The availability and accuracy of satellite positioning was assessed using a measurement of the number of visible satellites, position dilution of precision, respectively. The efficiency and reliability of GPS was evaluated using the GPS L1 carrier phase ambiguity resolution success rate. The simulator results showed that, with extra satellites and extra signals, QZSS not only improves the availability and accuracy, but also offers more efficient and reliable GPS in Japan and most East Asian regions.
