About positioning methods

Maps displays your location on the map using GPS, A-GPS, WLAN, or 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.
Wireless local area network (WLAN) positioning improves position accuracy when
GPS signals are not available, especially when you are indoors or between tall
buildings.
With cell ID based positioning, the position is determined through the antenna
tower your mobile device is currently connected to.
Depending on the available positioning method, the accuracy of positioning may
vary from a few metres to several kilometres.
When you use Maps for the first time, you are prompted to define the internet access
point to use to download map information, use A-GPS, or connect to a WLAN.
The availability and quality of GPS signals may be affected by your location, satellite
positions, buildings, natural obstacles, weather conditions and adjustments to GPS
satellites made by the United States government. GPS signals may not be available
inside buildings or underground.
