Modern UAVs do everything from treating fields with chemicals to observing wildlife. Swiss Air Rescue Service Rega announced that it has a drone developed by Swiss Air Rescue that can independently search and find missing people.
With a variety of built-in sensors, including visible, thermal and infrared cameras, as well as a phone tracking system, the drone can scan large areas of the terrain where there may be missing people.
Specially developed algorithms process data from various cameras installed on the Rega and identify situations of interest to rescuers, after which the information is sent to remote operators for processing. The drone can operate in poor visibility conditions, for example, forcing manned rescue helicopters to land.
Rega is equipped with a three-bladed rotor with a diameter of over 2 meters. It can fly at altitudes up to 100 meters using satellite navigation techniques to methodically survey a specific search area. Search sensors work in conjunction with systems to prevent collisions with power lines and other aircraft.
Rega is currently at the testing stage, and so far its "rescue" capabilities are limited to providing additional assistance to helicopters already in operation. He is expected to start a full-fledged independent search in 2020.
