Abstract: This application provide a positioning method, including: obtaining, by a first electronic device, a first location of a second electronic device; determining a plurality of candidate locations by using the first location as a center point; selecting a plurality of candidate positioning locations from the plurality of candidate locations based on elevations and azimuths of a plurality of satellites relative to the candidate locations, grid data corresponding to the plurality of candidate locations, and signal parameters of broadcast signals received by the second electronic device from the plurality of satellites; and correcting the first location based on the plurality of candidate positioning locations, to output a corrected second location.
