📚 SIRGAS 2025 Course at the University of Costa Rica

“Advanced Processing of Space Geodesy Data with Bernese 5.4: GNSS Techniques and Nonlinear Models”

From July 14 to 18, 2025, the course “Advanced Processing of Space Geodesy Data with Bernese 5.4” was held at the University of Costa Rica (UCR), with an emphasis on GNSS techniques and the fitting of nonlinear deformation models.

The course was taught by Dr. José Antonio Tarrío (President of SIRGAS WG I, USACH) and featured the collaboration of Dr. Mauricio Valera (President of SIRGAS WG II, UCR), integrating theory and practice throughout the week.

The following topics were covered during the training:

• Guided installation of Bernese BSW5.4 software
• Configuration and execution of GNSS geodetic campaigns
• Static relative phase processing in post-processing
  • Semi-free analysis
  • Geodetic datum fixes to International GNSS Service (IGS) stations
• Development and analysis of time series
• Fitting nonlinear models with FODITS, within the framework of the recent guidelines on kinematic reference frames defined by SIRGAS

The course included the participation of professionals from Costa Rica, Honduras, and Peru, reinforcing the regional commitment to the construction, maintenance, and updating of the geodetic reference frame of the Americas.

The final day was dedicated to the study of GNSS time series, including frequent seismic events in the Pacific Ring of Fire, making this week a training experience of great scientific and technical value for all attendees.
