Claim 12:
13. An electronic device, wherein the electronic device is a first electronic device, the first electronic device positions a second electronic device, the second electronic device receiving broadcast signals transmitted by a plurality of satellites, the electronic device comprising:
a memory storing instructions; and
at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
obtaining, by the first electronic device, a first location of the second electronic device;
determining, by the first electronic device, a plurality of candidate locations using the first location as a center point;
selecting, by the first electronic device, a plurality of candidate positioning locations from the plurality of candidate locations based on elevations and azimuths of the plurality of satellites relative to the plurality of candidate locations, grid data corresponding to the plurality of candidate locations, and signal parameters of the broadcast signals received by the second electronic device from the plurality of satellites, each grid data corresponding to each candidate location comprising location information and a sky blocking curve, a sky blocking curve of one candidate location indicating candidate elevations and candidate azimuths of a plurality of obstructions around the one candidate location; and
correcting, by the first electronic device, the first location of the second electronic device based on the location information of the plurality of candidate positioning locations and outputting a corrected second location of the second electronic device.
