About Positioning Methods - Nokia 500 User Manual

The compass has limited accuracy. Electromagnetic fields, metal objects, or other
external circumstances may also affect the accuracy of the compass. The compass should
always be properly calibrated.

About positioning methods

Maps shows your location on the map using GPS, A-GPS, WLAN, or network (cell ID) based
positioning.
A-GPS and other enhancements to GPS may require transferring small amounts of data
over the cellular network.

The availability and quality of GPS signals may be affected by your location, satellite
positions, buildings, natural obstacles, weather conditions, and adjustments to GPS
The global positioning system (GPS) is a navigation system that
uses satellites to work out where you are.
The Assisted GPS (A-GPS) network service retrieves location
information using the cellular network, and assists GPS in
calculating your current location.
Your phone is set up to use the Nokia A-GPS service, unless your
network service provider has its own A-GPS settings. To get the
assistance data to your phone, you need to be able to connect to
the internet. Your phone gets the data from the service only when
needed.
WLAN positioning improves positioning accuracy when GPS signals
are not available, especially when you are indoors or between tall
buildings.
With network (cell ID) based positioning, Maps locates you through
the cellular system your phone is currently connected to.
