Fraunhofer FHR-Newsletter 06/2025

Ladies and gentlemen, dear readers interested in the work of Fraunhofer FHR,

In our current issue of the newsletter, we would like to introduce you to exciting research projects from Fraunhofer FHR once again. We present new methods for removing space debris from orbit and showcase an energy-efficient high-frequency sensor for production.

We wish you an interesting read!

Warm regards,
Prof. Peter Knott and Prof. Dirk Heberling
Directors of Fraunhofer FHR

Removing Debris from Orbit

Numerous pieces of debris orbit the Earth – such as rocket upper stages. If they are to be actively removed, numerous issues must be clarified beforehand. Is the upper stage rotating? Or is its attitude towards Earth? Is it intact? Researchers at Fraunhofer FHR were able to successfully answer such questions for the Japanese space agency JAXA using the Tracking and Imaging Radar TIRA.

Energy-efficient high-frequency sensor for production

The microcontroller-based radar sensor µRADAS allows for micrometer-precise and non-destructive measurement of distances, contours, and surfaces in real-time and under challenging conditions. The system enables spot investigations as well as tomographic imaging, facilitating resource-efficient quality monitoring during production.
