Assisted GPS (A-GPS)

Your device also supports Assisted GPS (A-GPS).
A-GPS is a network service.
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.
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. To define an access point
for A-GPS, select Menu Applications Location and Positioning Positioning

Hold your device correctly

When using the GPS receiver, ensure you do not cover the antenna with your hand.
Establishing a GPS connection in the car, in bad weather conditions, or in a challenging
geographical environment may take longer.
