Key areas of expertise

Key areas of expertise are research within height systems, global reference network including surfaces for the ocean, gravity and geoids, physical modelling of the solid Earth and the state and development of the cryo- and hydrospheres. We work intensively in the Arctic regions, are dedicated to the national geodesy and provide global references.

Research areas

Gravity fields

Science and research within gravity fields and geoids at the highest level developing methodologies and sensors through international projects and with a special focus on Greenland and the Polar regions and support climate change science and geodynamics. (Illustration: NASA)

Hydrosphere

Develop and create reference surfaces for the ocean from gravity, mean sea surface and tides. Research on applying altimetry data to obtain information about ocean and inland waters. Long-term change of water level with special focus on coastal and polar regions as well as inland water. (Photo: DTU Space/Skyfish)

Geopositioning and Navigation

Research within height systems and global reference networks. Study the atmospheric effect on the GNSS signal. Engineering, data and sensor fusion to improve positional accuracy and robustness within drone navigation. (Photo: DTU Space)

Geodynamics

Physical modeling of the solid Earth, ice sheets and the oceans with the aim to develop dynamic reference frames and integrated models. The use of GNET data to understand the development ice-solid earth interaction. (Illustration: ESA)

Cryosphere

The Cryosphere group study of the present-day state of the cryosphere - levels of sea ice and land ice - and how to optimally map essential climate variables of the cryosphere from data gathered by satellite and airborne missions as well as in situ measurements. The main focus is on altimetry by airborne campaigns in the Arctic for observation and validation. (Photo: R. Tilling)
