About positioning methods

Maps displays your location on the map using GPS, A-GPS, WLAN, or network (cell ID)
based positioning.
The global positioning system (GPS) is a satellite-based navigation system used for
calculating your location. Assisted GPS (A-GPS) is a network service that sends you GPS
data, improving the speed and accuracy of the positioning.
WLAN positioning improves position accuracy when GPS signals are not available,
especially when you are indoors or between tall buildings.
With network (cell ID) based positioning, the position is determined through the
antenna system your mobile device is currently connected to.
To avoid network service costs, you can disable A-GPS, WLAN, and network (cell ID) based
positioning in your device positioning settings, but calculating your location may take
much longer. For more information about positioning settings, see the user guide of
your device.
The availability and quality of GPS signals may be affected by your location, satellite
positions, buildings, natural obstacles, weather conditions and adjustments to GPS
