IGETS is the International Geodynamics and Earth Tide Service of the International Association of Geodesy (IAG). The main objective of IGETS is to monitor temporal variations of the Earth gravity field through long‐term records from ground gravimeters, tiltmeters, strainmeters and other geodynamic sensors. IGETS continues the activities of the Global Geodynamics Project (GGP) to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network. Furthermore, IGETS continues the activities of the International Center for Earth Tides (ICET), in particular, in collecting, archiving and distributing Earth tide records from long series of gravimeters, tiltmeters, strainmeters and other geodynamic sensors. GFZ is the main Data Center and operates the IGETS data base of worldwide high precision SG records. EOST (Ecole et Observatoire des Sciences de la Terre, Strasbourg, France) is the secondary Data Center, The University of French Polynesia (Tahiti) and EOST (Strasbourg, France) are the two current Analysis Centers.

!!! >>> Duplicate to https://www.re3data.org/repository/r3d100011116 , this entry is no longer maintained <<< !!!! GGOS is the Global Geodetic Observing System of the International Association of Geodesy (IAG). It provides observations of the three fundamental geodetic observables and their variations, that is, the Earth's shape, the Earth's gravity field and the Earth's rotational motion. GGOS integrates different geodetic techniques, different models, different approaches in order to ensure a long-term, precise monitoring of the geodetic observables in agreement with the Integrated Global Observing Strategy (IGOS). GGOS provides the observational basis to maintain a stable, accurate and global reference frame and in this function is crucial for all Earth observation and many practical applications.
