Use of drones: How do you make something invisible visible?


Fire inspection, search for missing persons, transporting medicines: just a few of the activities for which drones are

As with any new technology, however, there are of course challenges that potential users have to face.

Because due to the low altitude at which drones usually operate, they are not detected by flight radar.

The information on manned air traffic is provided by air traffic control. To ensure that the
unmanned air traffic is also displayed to the drone pilot by the matchbox-sized
LTE transponder the size of a matchbox, the so-called HOD4Track, as well as separate ground

The HOD4Track is attached to the drone and receives the traffic information from the unmanned air traffic.

also sends its information to other road users via FLARM and receives ADS-B. Thus
the drone is also visible to them.
