Abstract:	In this paper, we present Japanese-regional ionospheric delay models and show a prediction method of the ionospheric delay. The ionospheric delay models derived in this paper are based on the SCHA (Spherical Cap Harmonic Analysis) as well as the SHF (Spherical Harmonic Function). Specially by using the SCHA ionospheric models, we investigate the ionospheric delay prediction and the prediction errors are examined through the experiments by using GPS observation data obtained from GEONET (Gnss Earth Observation NETwork) of the GSI (Geospatial Information Authority of Japan).
