Positioning (GPS)
You can use applications such as GPS data to calculate your
location or measure distances. These applications require a
GPS connection.
About GPS
The coordinates in the GPS are expressed 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
for its accuracy and maintenance. The accuracy of location
data can be affected by adjustments to GPS satellites made
by the
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 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 server > Access point. 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 for 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
Menu > Applications > Location and GPS data >
Options > Satellite status.
If your device has found satellites,
a bar for each satellite is shown in
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 your location, the bar colour
changes.
To view the positions of found satellites, select Chg. view.
Initially your device must receive signals from at least four
satellites to be able to calculate your location. When the
initial calculation has been made, it may be possible to
continue calculating your location with three satellites.
However, the accuracy is generally better when more
satellites are found.
If no satellite signal can be found, 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.
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, a message is displayed
showing the service that is making the request. Select
Accept to allow your position information to be sent or
Reject to deny the request.
