The Geospatial Information Authority of Japan (GSI) has operated the GPS Earth Observation Network system (GEONET) since 1996, as an indispensable national infrastructure for GPS surveying, crustal deformation monitoring and precise Location Based Services. With the advent of multi GNSS environment, advanced users require GNSS data other than GPS, such as GLONASS, Quasi Zenith Satellite System (QZSS), Galileo, and so on. In response to these demands, GSI updated all receivers and antennas of about 1,300 GEONET stations, and started to provide QZSS and GLONASS data from May 10, 2013, yielding a network-based RTK-GNSS positioning service for all over Japan by the private sector. GEONET is now literally a GNSS Earth Observation Network system.
