RESEARCH

The division conducts research relating to the Earth’s magnetic field and the use of satellite-based systems for technological innovations and space safety. Our work is based on measurements from satellites, drones, and ground stations and includes the design, manufacturing, and calibration of highly sophisticated drones and instruments for instance the FGE magnetometer which is installed in more than 250 geomagnetic observatories worldwide. The research in the division covers the six areas listed below.

Autonomous infrastructure

Covers the design, testing, and implementation of autonomous systems on land, sea, and in the air for scientific and other purposes.

Crustal magnetism and technology near-Earth magnetometry

Covers the development, testing, and application of new technologies for drone-based magnetic mapping of the Earth's crust, archaeology, subsurface ferrous pollution, and minerals. (Photo: DTU Space/A. Døssing)

Earth physics and machine learning

Covers the study of global-scale geophysical processes using satellite observations, computational models, inverse theory, and machine learning. (Illustration: ESA)

Ground-based magnetometry

Covers measurements of the Earth’s magnetic field taken from ground and the provision of high-quality geomagnetic instrumentation and data from over 20 magnetometer stations in Greenland, Faroe Islands, and Denmark. (Photo: DTU Space/M.G. Andersen)

Satellite magnetometry and Swarm DISC

We use magnetic field measurements taken by satellites like ESA’s Swarm spacecraft trio to study processes in Earth’s interior and its environment. (Illustration: ESA)

Space Weather and Space Safety

Covers activities and projects aimed at identifying, understanding, monitoring, and mitigating threats originating from space against the Earth, life, human technology, and infrastructure.

Among other things, DTU Space develops magnetometers in very high quality for use on the ground. They are in demand by institutions and national authorities across large parts of the world, where they are used for research and to detect changes in the magnetic field locally.
