1. An Unmanned Aerial Vehicle (UAV) positioning method, applied to a first UAV, the method comprising:
determining first information and second information of each of at least three second UAVs based on an Ultra Wide Band (UWB) signal in a case where a satellite positioning signal of the first UAV is lost, wherein the first information represents a relative distance between each second UAV and the first UAV, and the second information is carried in the UWB signal sent by the second UAV and represents real-time positioning information measured by the second UAV based on a satellite positioning signal; and
determining real-time positioning information of the first UAV according to the first information and the second information of each of the at least three second UAVs.
