Greenland, the world’s largest island, has one of the most challenging environments for geodetic measurements. Maintaining GNSS (Global Navigation Satellite Systems) stations here isn’t just about precision – it’s about ensuring data continuity in an area that’s constantly moving. This is the behind-the-scenes story of a 15,000 km journey around Greenland: five weeks of helicopter-bas ...[Read More]

Beyond navigation: How GNSS reveals Earth’s hidden secrets

Radosław Zajdel and Jan Douša November 28, 2025

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 th ...[Read More]

Seeing Geodesy clearly – suitable colours for effective and inclusive visualization

Effective scientific communication of geodetic research often relies on clear visualizations, and colours are needed to make complex data much easier to understand. However, traditional colormaps don’t always provide the needed clarity and can be especially challenging for people with colour-vision deficiencies (CVD). In this post, we will first describe what CVD is and how it is present in academ ...[Read More]

Geodesists on Tour: Taking Greta Gravimeter to the North

Rebekka Steffen and Holger Steffen September 27, 2024

Summer is coming to an end in the northern hemisphere, and it usually signals the end of the field season – at least in northern Europe. During the field season, we mostly take our absolute gravimeter (we call her Greta) to measure gravity at various locations across Sweden. Occasionally, we even take Greta to other countries – but that’s a story for another time. Who is G ...[Read More]
