Finnish permanent GNSS network: From dual-frequency GPS to multi-satellite GNSS

The Finnish Geodetic Institute (FGI) is building a new multi-satellite GNSS network in Finland. The renewal of the old GPS-only network FinnRef is funded by the Ministry of Agriculture and Forestry. The new network will consist of 19 stations collecting data from GPS, Glonass, Galileo and later also from Compass satellites. The network stations will be build on stable bedrock sites, equipped with Javad Delta-G3T receivers and individually calibrated Javad Dorne Margolin choke ring antennas covered with SCIGN radomes. Data will be transferred both as hourly files and real-time streams to the FGI and distributed to the users, co-operation partners and research institutions.
