In edition 02/2021 of the Feuerwehr Fachjournal we have published a second article on tethered drones. This second part deals with the technical background of tethering.
A drone can theoretically stay in the air 24/7, the most important requirement is of course an appropriate power source. In the article, Arne Glaser and Daniel Stahlmann (both ValoFly) describe the necessary components and their functions.
Issue 02/2021 of the Feuerwehr Fachjournal is available in specialized stores as of today, March 25, 2021.
