16th SIRGAS School: “VLBI and SLR Data Processing”
Com1, ILRS, IVS, 📅 Event Update📍 San Juan, Argentina | October 27 to November 1, 2025
The 16th SIRGAS School will be held at the Félix Aguilar Astronomical Observatory in San Juan, Argentina, from October 27 to November 1, 2025. This activity is part of the training initiatives promoted by SIRGAS, aimed at strengthening technical capacities in geodesy in Latin America.
The course will focus on the processing of VLBI (Very Long Baseline Interferometry) and SLR (Satellite Laser Ranging) data, two fundamental techniques for defining and maintaining global geodetic reference frames.
🎯 Course Objective
To provide the theoretical foundations and practical tools necessary for the analysis and processing of VLBI and SLR data, with an emphasis on their application in high-precision geodesy.
👥 Target audience:

Geodesy Cartoon Competition
ECS, GGOS, IAG, 📰 General NewsTurn Science into Smiles
Geodesy is the science of measuring the Earth’s shape, gravity field, and rotation. But what if we could make it exciting, fun, and easy for everyone to understand? That’s exactly why the International Association of Geodesy (IAG) and its Global Geodetic Observing System (GGOS) launched the Geodesy Cartoons initiative: to bring geodesy closer to the public through visually engaging and humorous illustrations.
The first Geodesy Cartoons were born from the creative mind of Riccardo Barzaghi, a geodesist and professor at the Politecnico di Milano, who pursues drawing as a hobby. To date, he has created three captivating cartoons on geodetic themes.
To build on this success, IAG and GGOS invite scientists, students, educators, and artists from all backgrounds to participate in the Geodesy Cartoon Competition. Whether you’re a researcher or simply someone with a creative idea and a love for drawing, this is your chance to inspire others and showcase the fascinating world of geodesy in a fun and accessible way.
Why share your vision through a cartoon?
Because science communication matters. With your Geodesy Cartoon, you can help people everywhere understand why geodesy is essential – from climate monitoring and navigation to disaster management and beyond.
What’s in it for you?
Winners can receive up to 900€ in prizes and additional benefits (e.g. free IAG Membership) and gain visibility across the global geodesy community. Every participant will also get a reserved spot at the IAG Geodesy Reception 2026 during the EGU General Assembly 2026 in Vienna.
Let your creativity lead the way.
No matter your style – digital or hand-drawn – all you need is a great idea, a simple and engaging message, and a Geodesy Cartoon that makes geodesy both fun and meaningful.
