Embodiment Construction
[0034] The present invention provides a method of simultaneously using GPS and the Beidou system to obtain positioning information, and adopting a method of storing historical positioning information to ensure that the positioning information of unmanned aerial vehicles is normal to the greatest extent. At the same time, when the positioning information is abnormal, the method of reading historical positioning information is adopted. Ensure that the aircraft can return to the starting position according to the historical trajectory when the positioning information is abnormal. The invention adds a radar ranging module to detect the distance between the unmanned aerial vehicle and obstacles in real time, and when a certain warning range is reached, the flight control module is notified to keep the unmanned aerial vehicle in a hovering state, effectively preventing the unmanned aerial vehicle from encountering obstacles There was an accident.
