Satellite Laser Ranging – How SLR Powers Geodesy
Discover Satellite Laser Ranging (SLR) – lasers from ground stations measure satellite and Moon positions with millimeter precision. SLR supports the Terrestrial Reference Frame, tracks Earth rotation, tectonic motion, improves gravity and sea level models, and tests relativity. Explore the science behind these precision measurements in our Geodesy Cartoon.

Geodesy Virtual School 2025 – Summary
The 2025 Geodesy Virtual School focused on reference frames and Earth system monitoring, held in five free online sessions coordinated from Argentina with support from SIRGAS, IAG, IUGG, and others. It featured 37 instructors and global participation, especially from the Americas. All lectures, in English or Spanish with subtitles, are available online, promoting inclusive, high-quality geodetic training worldwide.

Lost Without Geodesy
What happens if geodesy disappears? Phones, planes, and warning systems would fail. Our cartoon “Lost Without Geodesy” shows how vital this invisible science is. Geodesy powers GNSS, enabling precise positioning, earthquake monitoring, sea level studies, and more. Without it, GNSS would drift and global systems would collapse.

IAG Scientific Assembly 2025 – Third Circular
The IAG Scientific Assembly will take place in Rimini, Italy, on September 1–5, 2025. Abstract selection is complete, with 300 oral and 388 poster presentations scheduled. Early Career Scientists are encouraged to apply for IAG Travel Grants by July 31. Social events include an ECS Dinner and a Women in Geodesy Breakfast.

Call for Submissions: CLGE Young Surveyors Contest 2025
The CLGE Young Surveyors Contest 2025 invites students and early career geodesists to submit theses, papers, or projects for a chance to win up to €1500 and present at INTERGEO 2025. Open to geodesy and surveying professionals across Europe. Deadline: 28 July 2025
