Positioning (GPS)
You can use applications, such as GPS Data, to find your location or measure
distances and coordinates. These applications require a GPS signal.
Select Menu > Applications > GPS.
About GPS
The GPS coordinates 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 United States government,
which is solely 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 according to the United States
Department of Defense civil GPS policy and the Federal Radionavigation Plan.
Accuracy can also be affected by poor satellite geometry. The 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 the 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 Menu > Applications > GPS > 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, make sure you do not cover the antenna with your
hand. The antenna for the GPS receiver is in the top part of your phone.
Establishing a GPS connection may take 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.
