The invention discloses a multi-UAV anti-GPS-spoofing method in an intelligent cooperative environment. The method comprises steps of: firstly, recording the GPS signal information of each UAV in a UAV fleet and exchanging information among the UAVs; causing the airborne cooperative control algorithm of each UAV to predict the position of the UAV at the next moment through the fleet GPS information; updating the GPS information by the predicted position and the next moment and determining whether the UAV has potential GPS spoofing; if it is determined that GPS spoofing may be encountered, performing triangulation by using infrared positioning to determine the exact position of the UAV and correcting the GPS signal, otherwise, repeating the above steps until the end of the flight. The method can ignore specific GPS spoofing details and directly detect whether GPS spoofing has occurred based on the cooperative control mechanism, can handle the situations where multiple UAVs simultaneously suffer GPS spoofing. is easy to operate and practical.
Description
Technical field [0001] The invention belongs to the technical field of automatic control and safety of unmanned aerial vehicles, and specifically relates to an anti-GPS spoofing method for multiple drones in an intelligent collaborative environment, which is used for detecting and identifying GPS spoofing under multiple drones formation flying, and further Eliminate the influence of GPS spoofing on UAV formation flying. Background technique [0002] Today, with the gradual maturity of drone technology, drones have become more and more deeply involved in all aspects of people's lives. Including drone aerial photography, geological surveying and mapping, remote sensing, and access to key information in geological disaster areas. At the same time, as a new type of aircraft, UAVs are also favored by the military for their small size, low cost, easy use, low requirements for the combat environment, and strong battlefield survivability. Countries are stepping up the development of ind...
