Traditionally geodesy is the science of the measurement and the mapping of the Earth’s surface. Since the surface is mainly shaped by the Earth’s gravity field the classical definition includes the Earth’s gravitational potential. Observing the Earth's figure, the orientation and rotation as well as the gravity field, geodesy today provides spatial and temporal patterns of geophysical processes within the Earth system such as sea-level rise, tides, melting of continental ice masses, changes in global water circulation and in the atmosphere or deformations of the solid Earth. Consequently, the Geodesy Division covers activities on the whole spectrum of modern geodetic Earth system modelling from the measurement systems to the investigation of geophysical processes.

Beyond navigation: How GNSS reveals Earth’s hidden secrets

Part 1 – the global case When you check directions on your smartphone or track your morning run, you’re tapping into a global infrastructure that has revolutionized not just navigation, but our understanding of Earth itself. What began as military technology has evolved into powerful scientific tools that confirm longstanding theories and reveal previously unobservable phenomena. In this post, we’ll explore how this remarkable technology developed into the Global Navigation Satellite System (GNSS) we know today—an intricate network of satellites …


Expanding the picture: Franck Ghomsi

What does a geodesist look like? And what happens if you don’t “look the part”? Today, Franck Ghomsi, a Black African scientist, takes us along on his journey between South Africa, Canada and Cameroon. Franck does not only research the impact of climate change on coasts with geodetic techniques, but at the same time became an expert in self-motivation, battling racism and fighting against the windmills of visa acquisition. Hi Franck, thank you for sharing your story with us and …


EGU Campfire Geodesy – Share Your Research – 14th Edition

We are excited to announce the 14th edition of Geodesy Campfire – Share Your Research in November. The Geodesy EGU Campfire Events “Share Your Research” give (early career) researchers the chance to talk about their work. We have two exciting talks by our guest speakers, Betty Heller-Kaikov and Pingping Huan. Below, you can find the details of the topics awaiting us. We will have time to network after the presentations. Please join us on Zoom on 28th November from 10:00 …


Climbing Through a PhD – Mental Health on the Way to the Summit

Imagine you are going on a long mountain tour. Your backpack is heavy, the path is steep, and although you have been walking for hours, all you can see ahead of you is the next climb. Doing a PhD is like climbing such a mountain. It can feel exhausting, there is always the next challenge ahead and the finish line seems to never get closer. Self-doubt and the feeling of not doing enough accompanies many PhD students along their journey. …
