The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy IAG. IGETS continues the activities of the Global Geodynamics Project (GGP) between 1997 and 2015 to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network.

The Conrad Observatory (CO) is located at Trafelberg, Lower Austria, about 50 km south-west of Vienna at an elevation of about 1050m. Three different geological formations are found in the vicinity of the CO: the Gutenstein Formation, Reifling Formation, and Wetterstein Limestone. The observatory is part of a large underground installation covering the full geophysical monitoring program including seismology, gravity, meteorology and geomagnetism. It includes two main facilities: (1) The seismo-gravimetric observatory (SGO), which was opened in 2002, and (2) the geomagnetic observatory (GMO), officially opened in 2014. Temporal variation of gravity is monitored at CO since autumn 2007 by the Superconducting Gravimeter GWR C025 (until November 2018) and, after a longer interruption, by GWR iGrav 050. The time series of gravity and barometric pressure from the iGrav SG 050 starts in April 2024. The time sampling of the raw gravity and barometric pressure data of IGETS Level 1 is 1 second and 1 minute. For a detailed description of the IGETS data base and the provided files see Voigt et al.
