The Rega drone can autonomously scan large search areas and is equipped with various sensors, such as a thermal camera. The Rega drone is deployed on missions to search for missing, injured or ill persons to supplement the conventional resources – for example, if the helicopter has to remain on the ground due to poor visibility. As a result, Rega has at its disposal an additional device to help it search for people in distress.
The Rega drone has a rotor diameter of 2.2 metres and is 2.2 metres long and 71 centimetres high. It is driven by a twin-shaft engine, which means that it still has sufficient power reserves even at high altitudes. With a total weight of around 25 kilograms, it can be deployed for a variety of uses.
If necessary, the drone can also operate without visual contact with the pilot using the so-called BVLOS (Beyond Visual Line of Sight) procedure. This requires the connection to the drone to also be maintained without directly being able to see it. In the case of the Rega drone, this happens via the mobile radio network.
The signals from the infrared camera and the camera with visual contact are categorised with the aid of a self-learning algorithm. The image areas in which, based on the pixel pattern, the algorithm "presumes" a person is located are relayed to the operator on the ground, who then examines this footage manually.
