The accuracy can be affected by poor satellite geometry. The more
satellites the GPS module can detect, the better the accuracy. The internal
antenna of the GPS module, located on the same side as the Nokia logo,
should face upwards for proper functioning. Some car windshields and
windows may contain metal for heat reflection or defogging purposes,
that may block or attenuate the satellite signals.
In addition, the GPS determines your direction on the basis of your
movement. Therefore, the GPS cannot detect which way you are facing if
you are not moving.
Note: The GPS 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.
Therefore, 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 support location
of the phone by emergency operators.
