Abstract: A positioning using Global Navigation Satellite System (GNSS) requires some augmentation systems in civil air navigation. Satellite- based augmentation system (SBAS) is one of the augmentation system. The SBAS augments GNSS and improves an accuracy and an integrity of aviation user positioning. Since, conventional SBAS augments L1 single frequency positioning of single GNSS (GPS), it needs to provide Ionospheric correction. Since, to generate the Ionospheric correction needs many ionosphere pierce points in their Service Area, the SBAS needs many monitor stations on the ground. Thus, the conventional SBAS is difficult to provide a wide, like a global, Service Area. On the other hand, Next-generation SBAS Standards have been under development at International Civil Aviation Organization (ICAO). The New SBAS augments a positioning using Dual-frequency signals of Multi-constellation GNSS. Thus, we call it DFMC SBAS. DFMC SBAS don’t provide the Ionospheric correction thanks to using Dual-frequency signal. Therefore, DFMC SBAS don’t need the many monitor station, and it is easy to provide the globally wide Service Area augmentation. Here, authors have been developed a prototype system of DFMC SBAS for validation of the Standards under development. Thus, this paper describes a performance of DFMC SBAS prototype system that provides global wide Service Area by using global monitor stations provided by Quasi-Zenith Satellite System (QZSS).
