The Italian Geodetic Observatory in Antarctica focuses on the establishment and maintenance of the geodetic framework in Antarctica, in order to provide measurements and analysis for the characterization of neo-tectonic of a large area of Northern Victoria Land. The Observatory is based on continuous GNSS (Global Navigation Satellite System) measurements, for the definition of a three-dimensional reference, and tide gauge measurements, for the definition of an absolute local and global elevation reference model. The GNSS measurements are carried out on 27 stations creating the VLNDEF network (Victoria Land Network for DEFormation control).

The VLNDEF observations are processed for scientific purposes by the IGOA itself as well as shared with further international centres. As an example visit the NGL – Nevada Geodetic Laboratory website, that includes IGOA stations and data withihn the global network. For accessing the time series of VLNDEF stations, please visit the NGL GPS Networks Map.

The IGOA data are shared to the scientific community and are accessible through the download page of this website.
