Positioning method and electronic device

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.

A chip system is applied to a first electronic device, the first electronic device positions a second electronic device, the second device receiving broadcast signals transmitted by a plurality of satellites, the chip system comprising:

• a circuit;
• and
• one or more processors coupled to the interface circuit, the one or more processors being interconnected by a cable;
• the interface circuit is configured to receive a signal from a memory of the first electronic device and send the signal to the processor, the signal comprising computer instructions stored in the memory, and the one or more processors execute the computer instructions, the first electronic device performs the steps of:
• obtaining a first location of the second electronic device;
• determining a plurality of candidate locations 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 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 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.
