Claim 10:
11. A non-transitory computer-readable storage medium, the computer-readable storage medium storing one or more computer programs and one more processor which execute the one or more computer programs to perform:
acquiring target position information of a terminal;
selecting, from a preset satellite visible window table and according to the target position information, an ephemeris data record whose position information matches the target position information to obtain a target record set;
selecting N satellites according to the ephemeris data record in the target record set to form a visible satellite list, wherein N is an integer greater than or equal to 4;
positioning according to the N satellites in the visible satellite list;
wherein the ephemeris data record in the satellite visible window table comprises ephemeris data directly downloaded by the terminal from a server or an ephemeris data converted by the terminal according to ephemeris data periodically acquired from the server; and
the ephemeris data record further comprises a satellite number, a satellite elevation angle and a record timestamp, wherein the position information of the ephemeris data record is information about a position where a terminal generating the ephemeris data record is located when the ephemeris data record is generated, and the record timestamp is time when the ephemeris data record is generated.
