The rescue system “LuckyBeak” is designed to provide precision landing for UAS with the weight of 2.5 to 10 kg under normal and emergency conditions. “LuckyBeak” is brought into action by operator or autopilot command. Moreover, “LuckyBeak” can be optionally outfitted with its own programmable controller, which ensures automatic deployment in case of descending below a specified altitude or any other preset conditions.
