SCAR-GIANT (Geodetic Infrastructure in Antarctica)

 Colonel Norbertino Suárez, Servicio Geográfico Militar

The main objective of the GIANT Project is to establish and maintain a high-precision geodetic infrastructure, whose signals, milestones or reference stations for continuous observation(CORS), as part of the activities of the Scientific Committee on Antarctic Research (SCAR) based on Global Positioning Satellite Systems (GNSS), are part of the Geodetic Reference Framework (GRF) that materializes the Geodetic Reference System (GRS) for precise positioning (geographic or Cartesian coordinates and height) or Georeferencing, of any geographic object located on the terrestrial surface.

The Military Geographic Service (SGM) has installed and observed semi-permanent and permanent Passive Stations (milestones), as well as Active Stations (CORS), which are used as reference for topographic, geodetic, photogrammetric and geophysical surveys, for technical and scientific purposes, such as cartographic production, georeferencing of objects in the framework of other research projects, control of tectonic plates movement, among others.

The CORS called UYBA, installed 2 years ago in the vicinity of the Artigas Antarctic Scientific Base (BCAA), and integrated to the National Active Geodetic Network of our country (REGNA-ROU), and integrated into the Geocentric Reference System of the Americas (SIRGAS), allows the determination of high-precision coordinates in Real Time and Post-Process for any user of this technology, free and at no cost. Moreover, through observations of the station position taken every one second, with high precision, allows the monitoring of bark movements. In the near future, it is planned to install in the vicinity of the ECARE Station, Passive and Active Geodetic Stations, the latter semipermanently at the beginning, to then evolve into a permanent CORS.

The activities carried out within the framework of the SCAR-GIANT Project, and in particular by the SGM in this regard, are closely related to the recommendations set out in the United Nations General Assembly Resolution of February 26, 2015 (document A / 69 / L.53) on the development of the Global Geodetic Reference Framework (GGRF) and Global Geospatial Information Management (GGIM) to meet the Sustainable Development Goals (SDG), being the GGRF one of the data to generate and maintain.
