Galileo is the European satellite navigation system developed and operated by the European Union (EU) in cooperation with the European Space Agency (ESA). Galileo is a decisive step for Europe's technological sovereignty and economic development. It provides precise and reliable global positioning, which is essential for a wide range of applications.
The Geodetic Reference Service Provider (GRSP) is a key element of the Galileo Ground Mission Segment (GMS), providing satellite orbits, clock corrections and atmospheric parameters, which are important validation products for Galileo's operations. Based on station coordinates for Galileo Sensor Stations and stations of the International GNSS Service, GRSP realizes the Galileo Terrestrial Reference Frame (GTRF). In this reference frame, the information broadcast by the Galileo satellites is delivered to users worldwide. GRSP is jointly operated by GFZ, ESA/ESOC (Germany), University of Bern (Switzerland), BKG (Germany), IGN (France) as part of the Galileo Service Operator (GSOp).
