Availability & access
- Free access to RINEX files through the official portal.
- Real-time corrections provided by the RAMSAC-NTRIP service, also free of charge.
Coverage & scale
- National network of more than 100 continuously operating reference stations.
- Integrated into the South American Geocentric Reference System (SIRGAS) and aligned with the International Terrestrial Reference Frame (ITRF).
Typical use cases
- Surveying, mapping, and engineering projects.
- Scientific research and geodetic monitoring.
- Maintenance and densification of Argentina’s national geodetic reference frame.
How it’s used in practice
- Surveyors connect GNSS rovers to the RAMSAC-NTRIP caster for real-time RTK corrections.
- Post-processing users download RINEX files for static and kinematic workflows.
Notes
The network has been active since the late 1990s and is continuously expanding and modernizing.
