The coordinates in the GPS are expressed in degrees
and decimal degrees format using the international
WGS-84 coordinate system.
The Global Positioning System (GPS) is operated by the
government of the United States, 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 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.
The GPS receiver should only be used outdoors to allow
reception of GPS signals.
Any 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.
To enable or disable different positioning methods,
such as Bluetooth GPS, select Menu > Tools >
Settings > General > Positioning > Positioning
methods.
About satellite signals
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.
• If the weather conditions are bad, the signal
strength may be affected.
• Establishing a GPS connection may take from a
couple of seconds to several minutes.
Satellite status
To check how many satellites your device has found,
and whether your device is receiving satellite signals,
select Menu > Tools > GPS data > Position >
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 the
coordinates of your location, the bar turns black.
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.
Positioning settings
Select Menu > Tools > Settings > General >
Positioning.
To use a specific positioning method to detect the
location of your device, select Positioning methods.
To select a positioning server, select Positioning
server.
