About positioning methods
Maps displays your location on the map using GPS, A-
GPS, 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.
When you use Maps for the first time, you are prompted
to define an internet access point to download map
information or use A-GPS.
indicates the availability of the satellite
signals. One bar is one satellite. When the device is
searching for satellite signals, the bar is yellow. When
there is enough data available to calculate your
location, the bar turns green. The more green bars, the
more reliable the location calculation.
The Global Positioning System (GPS) is operated by the
government of the United States, which is solely
responsible for its accuracy and maintenance. The
accuracy of location data can be affected by
adjustments to GPS satellites made by the United
States government and is subject to change with the
United States Department of Defense civil GPS policy
and the Federal Radionavigation Plan. Accuracy can
also be affected by poor satellite geometry. Availability
and quality of GPS signals may be affected by your
location, buildings, natural obstacles, and weather
conditions. GPS signals may not be available inside
buildings or underground and may be impaired by
materials such as concrete and metal.
GPS should not be used for precise location
measurement, and you should never rely solely on
location data from the GPS receiver and cellular radio
networks for positioning or navigation.
The trip meter has limited accuracy, and rounding
errors may occur. Accuracy can also be affected by
availability and quality of GPS signals.
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.
Use the compass
If your device has a compass, when activated, both the
arrow of the compass and the map rotate
automatically in the direction to which the top of your
device is pointing.
Select Menu > Maps and My position.
Activate the compass — Select
.
Deactivate the compass — Select
again. The map
is oriented north.
