Some results of application studies of GPS retrieved tropospheric delays on weather prediction (GPS Meteorology) conducted in Japan are outlined. It is suggested that the nationwide GPS array in Japan (GEONET) of Geographical Survey Institute (GSI) is an excellent all-weather water vapor sensor applicable to regional weather predictions by Japan Meteorological Agency (JMA). It is also found that a sophisticated analytical model developed for GPS meteorology can remove drifts due to water vapor delay appearing in the horizontal solution of GPS positioning in summer.
