Positioning methods

Your phone shows your location on the map using GPS, GLONASS, A-GPS, Wi-Fi, or network
(Cell ID) based positioning.
The availability, accuracy and completeness of the location information depend on, for
example, your location, surroundings, and third party sources, and may be limited. Location
information may not be available, for example, inside buildings or underground. For privacy
information related to positioning methods, see the Microsoft Mobile Privacy Policy.
The Assisted GPS (A-GPS) network service and other similar enhancements to GPS and
GLONASS retrieve location information using the cellular network, and assists in calculating
your current location.
A-GPS and other enhancements to GPS and GLONASS may require transferring small amounts
of data over the mobile network. If you want to avoid data costs, for example when traveling,
you can switch the mobile data connection off in your phone settings.
Wi-Fi positioning improves positioning accuracy when satellite signals are not available,
especially when you are indoors or between tall buildings. If you're in a place where the use
of Wi-Fi is restricted, you can switch Wi-Fi off in your phone settings.
The trip meter may not be accurate, depending on the availability and quality of your satellite
connection.
