Scientists Swiss Technical High School in Zurich presented a draft of a small unmanned aerial vehicle, which carries an autonomous navigation without GPS satellite navigation and remote control systems for ground operators.
The developers note that, depending on the terrain value of GPS-navigation error can reach 70 meters, so, for example, in large cities with tall buildings, this technology may prove to be absolutely useless. This deprives the unmanned aircraft is fully autonomous mode. Autonomous functions does not help, and attachment to land-based systems, remote control operators. To meet these challenges and overcome constraints imposed by existing technologies, Swiss scientists suggest their own solution.
