About positioning methods
Your phone shows your location on the map using GPS, A-GPS, Wi-Fi, or cellular
positioning.
GPS The global positioning system (GPS) is a navigation system that
uses satellites to work out where you are.
A-GPS The Assisted GPS (A-GPS) network service retrieves location
information using the cellular network, and assists GPS in
calculating your current location.
Wi-Fi Wi-Fi positioning improves positioning accuracy when GPS signals
are not available, especially when you are indoors or between tall
buildings.
You can also switch Wi-Fi and cellular positioning off in your phone
settings.
Cell ID With network (cell ID) based positioning, your phone locates you
through the cellular system your phone is currently connected to.
A-GPS and other enhancements to GPS may require transferring small amounts of
data over the cellular network. If you want to avoid data costs, for example when
travelling, you can switch the mobile data connection off in your phone settings.
The availability, accuracy and completeness of the location info depend on, for
example, your location, surroundings, and third party sources, and may be limited.
