Nation-wide RTK-GPS based on FKP method and applications for human navigation and location based services

A high accuracy positioning service named PAS, based on nationwide RTK-GPS and FKP method, has been realized in Japan, and commercially operated since September 2003. Cm-level accuracy is obtained and uniformity in the service area is also validated. Application to a human navigation prototype system is also shown with a real image on a cellular telephone, and will be linked to the PAS system to serve as a location base service in the near future
