The division conduct research in stars, galaxies, planets, exoplanets, the Solar System and the Universe as a whole, as well as the interaction between space and the Earth's atmosphere.

The department works with testing, research and development within electromagnetic field theory, antenna technology, meta-materials, microwave technology and terahertz technology.

The division researches in observation, surveying and mapping of the Earth concerning primarily climate change. Other focus areas are measuring and observing the Earth's gravitational field, displacements in the Earth's crust, ice cover changes, soil and sea surface levels and land uplift.

The division uses satellites and ground-based measuring stations to explore and map the Earth's magnetic field. The research provides insight into changes in the magnetic field and processes coupled to the sun.

Research and development activities in the division focus on high-precision instrumentation systems for space missions and on research based on data gathered via these instruments.

The division deals with research, development and use of microwave sensors. We research both passive and active sensors - which are microwaves, radiometers and radars - that are used to observe the earth's surface.
