Assisted Gps (A-Gps); Hold Your Device Correctly; Tips On Creating A Gps Connection - Nokia N97 User Manual

Assisted GPS (A-GPS)

Your device also supports assisted GPS (A-GPS).
A-GPS requires network support.
Assisted GPS (A-GPS) is used to retrieve assistance data over
a packet data connection, which assists in calculating the
coordinates of your current location 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.
To disable the A-GPS service, select

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. The access point for A-GPS can be
defined in positioning settings. A wireless LAN (WLAN) access
point cannot be used for this service. Only a packet data
internet access point can be used. Your device asks you to
select the internet access point when GPS is used for the first
time.
