9th SIRGAS School on Reference Systems and Reference Frames 2026

From October 19 to 30 and November 9 to 13, 2026, the 9th SIRGAS School on “Reference Systems and Reference Frames” will be held. The School will be offered in a hybrid format: the theoretical component will be delivered online, while the practical component will take place in person at the Faculty of Engineering of the University of the Republic (Universidad de la República), Montevideo, Uruguay. The School will be conducted exclusively in Spanish. 

The program consists of ten days dedicated to the theoretical foundations of Reference Systems and Reference Frames, followed by five days of practical exercises focused on the computation, processing, and adjustment of observations, GNSS network adjustment using scientific software, and the processing, computation, and adjustment of gravimetric data. The School is intended for advanced professionals, early-career scientists, and staff members from national agencies seeking training in the fundamental topics of physical and geometric geodesy.

  • Identify the metadata required for processing GNSS and gravimetric data. 
  • Understand the details of GNSS and gravimetric data processing. 
  • Set up a GAMIT/BERNESE processing workflow using their own data. 
  • Use GLOBK/BERNESE to perform daily and weekly combinations. 
  • Densify IGS20 using the provided sample data. 
  • Plan gravimetric measurement campaigns. 
  • Process gravimeter readings into mGal units and apply the necessary corrections to the observations. 
  • Process, adjust, and predict gravimetric observations. 
  • Compute and interpret gravity anomalies.
