Provided are an unmanned aerial vehicle positioning method, an unmanned aerial vehicle and a machine-readable storage medium. The positioning method is applicable to an unmanned aerial vehicle. The positioning method comprises: receiving ADS-B signals (automatic dependent surveillance-broadcast) from at least three aircraft (step S1); according to the ADS-B signals, determining positions of the at least three aircraft (step S2); and according to the positions of the at least three aircraft, determining the position of an unmanned aerial vehicle (step S3). The position of an unmanned aerial vehicle can be determined according to ADS-B signals from aircraft rather than according to a GPS signal, so that even where there is interference to the GPS signal or the GPS signal is tampered with, the position of the unmanned aerial vehicle can be accurately determined.
