Positioning (GPS)
You can use applications such as GPS data to
determine your location, or measure distances and
coordinates. These applications require a GPS
connection.
About GPS
The coordinates in the GPS are expressed in the
degrees and decimal degrees format using the
international WGS-84 coordinate system. The
availability of the coordinates may vary by region.
The Global Positioning System (GPS) is operated by
the government of the
responsible for its accuracy and maintenance. The
accuracy of location data can be affected by
adjustments to GPS satellites made by the United
States government and is subject to change with
the United States Department of Defense civil GPS
policy and the Federal Radionavigation Plan.
Accuracy can also be affected by poor satellite
geometry. Availability and quality of GPS signals
may be affected by your location, buildings, natural
obstacles, and weather conditions. GPS signals may
not be available inside buildings or underground
and may be impaired by materials such as concrete
and metal.
GPS should not be used for precise location
measurement, and you should never rely solely on
location data from the 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 is 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 Menu >
Applications > 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. 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.
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
If your device cannot find the satellite signal,
consider the following:
● If you are indoors, go outdoors to receive a better
signal.
● If you are outdoors, move to a more open space.
● Ensure that your hand does not cover the GPS
antenna of your device.
● If the weather conditions are bad, the signal
strength may be affected.
● Some vehicles have tinted (athermic) windows,
which may block the satellite signals.
Check satellite signal status
To check how many satellites your device has found,
and whether your device is receiving satellite
signals, select Menu > Applications > GPS data
and Options > Satellite status.
If your device has found
satellites, a bar for each
satellite is displayed in the
satellite information view.
The longer the bar, the
stronger the satellite
signal is. When your device
has received enough data from the satellite signal
to calculate the coordinates of your location, the bar
colour changes.
Initially, your device must receive signals from at
least four satellites to be able to calculate the
coordinates of your location. When the initial
calculation has been made, it may be possible to
continue calculating the coordinates of your
location with three satellites. However, the
accuracy is generally better when more satellites
are found.
Position requests
You may receive a request from a network service
to receive your position information. Service
providers may offer information about local topics,
such as weather or traffic conditions, based on the
location of your device.
When you receive a position request, the service
that is making the request is displayed. Select
Accept to allow your position information to be
sent or Reject to deny the request.
Landmarks
Select Menu > Applications > Landmarks.
With Landmarks, you can save the position
information of specific locations in your device. You
can sort the saved locations into different
categories, such as business, and add other
information to them, such as addresses. You can use
your saved landmarks in compatible applications,
such as GPS data.
GPS coordinates are expressed in the degrees and
decimal degrees format using the international
WGS-84 coordinate system.
Select Options and from the following:
● New landmark — Create a new landmark. To
