Positioning
The Global Positioning System (GPS) is a worldwide radio
navigation system that includes 24 satellites and their
ground stations that monitor the operation of the satellites.
A GPS terminal, such as the internal GPS receiver in Nokia
N810 Internet Tablet products, receives low-power radio
signals from the satellites, and measures the travel time of
the signals. From the travel time, the GPS receiver can
calculate its location to the accuracy of meters.
The coordinates in the GPS are expressed in degrees and
decimal degrees formats 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.
GPS should only be used as a navigation aid. It should not
be used for precise location measurement and you should
never rely solely on location data from the GPS receiver for
positioning or navigation.

The procedure for using a GPS receiver with your Internet
tablet may vary according to the product model:
Nokia N800 Internet Tablet—You must use an external GPS
receiver with your device. Pair a compatible GPS receiver with
