PPP-AR Server Network	PPP-AR Client Stations

Real-time coordinate solution of client stations (constrain of 100 m/s）:
0180 (100 km), 1121 (900 km from reference network)

Server network: number of ambiguity residual

Distribution map of GEONET stations used for PPP-AR processing demonstration (real-time data is purchased from NGDS). Red circles (Hokkaido, northern Japan) and blue circles are stations used for generation of PPP-AR correction and client test stations, respectively.
