Embodiment Construction
[0062] The present invention provides a high-precision positioning method that protects user location privacy:
[0063] 1. The terminal only reports the ID of the mobile communication base station, not the NMEA GGA data;
[0064] 2. The server pre-establishes a database corresponding to the ID of the mobile communication base station and the geographic location of the mobile communication base station;
[0065] 3. The server finds the geographic location of the mobile communication base station according to the mobile communication base station ID reported by the terminal;
[0066] 4. The server matches the corresponding virtual reference station grid according to the geographical location of the mobile communication base station;
[0067] 5. According to the found virtual reference station grid, broadcast the differential correction data corresponding to the grid to the terminal.
[0068] Note 1: Reporting the mobile communication base station ID requires a two-way interact...
