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.
Different positioning methods can be enabled or disabled in
positioning settings.

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
GPS data and Options > Positioning settings >
Positioning methods > Assisted GPS > Disable.
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. Only a packet data internet
28
access point can be used. Your device asks you to select the
internet access point when GPS is used for the first time.

Hold your device correctly

When using the GPS receiver, ensure you do not cover the
antenna with your hand.
Establishing a GPS connection may take from
a couple of seconds to several minutes.
Establishing a GPS connection in a vehicle
may take longer.
The GPS receiver draws its power from the
device battery. Using the GPS receiver may
drain the battery faster.
Tips on creating a GPS connection
Check satellite signal status
To check how many satellites your device has found, and
whether your device is receiving satellite signals, select
Applications and GPS data > Position > Options >
Satellite status.
If your device has found satellites,
a bar for each satellite is shown in
> Applications >
the satellite info view. The longer
the bar, the stronger the satellite
signal. When your device has
received enough data from the
satellite signal to calculate the coordinates of your location,
the bar turns blue.
