About positioning methods
Maps displays your location on the map
using GPS, A-GPS, Wi-Fi, 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.
Wi-Fi network 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 cellular phone is
currently connected to.
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
Wi-Fi network.
To avoid network service costs, you can
disable A-GPS, Wi-Fi, 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 satellites made by
the United States government. GPS
signals may not be available inside
buildings or underground.
Do not use GPS for precise location
measurement, and never rely solely on
