Die optische Verbindung im freien Raum ist eine vielversprechende Lösung für die Übertragung von Signalen zwischen Satelliten in zukünftigen SAR-Satellitenformationen (Synthetic Aperture Radar). Ziel ...

Drones flew between the wind turbines at altitudes of up to 250 metres, positioning themselves in two lines of five.

In spring 2025, a swarm of drones carried out measurements directly in front of and behind the OPUS 1 and OPUS 2 wind turbines at DLR's WiValdi wind energy research farm in Krummendeich.

Each individual drone weighs less than one kilogram and is optimised for wind measurements.
