Global positioning system (GPS)
The GPS (global positioning system) is a
worldwide satellite-based radio
navigation system.
A GPS terminal can calculate its location
to an accuracy of 10 meters. The accuracy
depends on the number of satellites, the
signals of which the GPS module receives.
In optimal conditions, the accuracy may
be within a few meters.
The antenna of the GPS module is located
under the Nokia logo, and it should face
upwards. Some car windshields and
windows may contain metal, which may
block or weaken the satellite signals.
If you stand still, GPS cannot detect which
way you are facing, because it determines
your direction on the basis of your
movement.
Note:
The GPS (global positioning
system) is operated by the
United States government, which is solely
responsible for accuracy and maintenance
of the system. 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 buildings and natural
obstacles, as well as weather conditions.
The GPS receiver should only be used
outdoors to allow reception of GPS
signals.
GPS should not be used for precise
location measurement, and you should
never rely solely on location data from the
GPS receiver. This GPS receiver does not
