Positioning (GPS)
when your device is receiving signals from
satellites.
When you activate A-GPS, your device receives
useful satellite information from an assistance data
server over the cellular network. With the help of
assisted data, your device can obtain the GPS
position faster.
Your device is preconfigured to use the Nokia A-GPS
service, if no service provider-specific A-GPS settings
are available. The assistance data is retrieved from
the Nokia A-GPS service server only when needed.
You must have an internet access point defined in
the device to retrieve assistance data from the
Nokia A-GPS service over a packet data connection.
