SIRGAS 2025 Virtual School:

“Terrestrial Reference Frame. Geodynamic and Atmospheric Monitoring”

The SIRGAS 2025 Virtual School, titled “Terrestrial Reference Frame. Geodynamic and Atmospheric Monitoring,” was held with great success on June 3, 5, 6, 10, and 12, 2025. This training event brought together more than 330 online participants and reached a peak of 500 registrants from 37 countries, consolidating its position as a benchmark experience in the region.

During five intensive days, 30 international specialists offered a total of 37 technical presentations in audiovisual format, rigorously coordinated in content, duration, and quality. The sessions addressed key topics for the geodetic community in the Americas, including:

Global and continental geodetic infrastructure
Space-based techniques such as GNSS, VLBI, SLR, and DORIS
ITRF reference frames and their integration with the ICRF
Atmospheric monitoring (ZTD, VTEC) and geodynamic deformations
Use of observatories such as AGGO
Tools for time series analysis and precise positioning

The event was organized by SIRGAS and scientifically coordinated by María Virginia Mackern, who also translated the subtitles between English and Spanish, facilitating the dissemination of content throughout the region. The USACH provided the virtual platform thanks to the support of the Chair of WG I, José Antonio Tarrío Mosquera, while the Military Geographic Institute of Uruguay guaranteed the simultaneous broadcast on YouTube and Facebook.

Thanks to this collective effort, the school’s content is now openly available on the SIRGAS YouTube channel: YouTube SIRGAS Americas

This school not only reinforced SIRGAS’s commitment to ongoing training but also demonstrated the high technical level of its member countries, once again demonstrating the region’s ability to lead the challenges of present and future geodetic science.
