GEONET GPS-TEC maps: Final | Quasi-Realtime | Realtime



GEONET realtime TEC maps over Japan
(latest 6 hours with 10-minute interval)

Japanese / English

The two-dimensional maps of total electron content (TEC), detrended TEC, rate of TEC change index (ROTI), and loss of lock on GPS signals (LOL) are made by NICT under collaboration with Electronic Navigation Research Institute (ENRI), Kyoto University and Nagoya University. The TEC data and LOL information are calculated by ENRI using GEONET GPS data operated by Geospatial Information Authority of Japan. The realtime plots in this site have not been fully calibrated. If you have any questions or comments, please e-mail to .
