The coordinates in the GPS are expressed in the degrees and decimal degrees formatusing the international WGS-84 coordinate system. The availability of thecoordinates may vary by region.The Global Positioning System (GPS) is operated by the government of the UnitedStates, which is solely responsible for its accuracy and maintenance. The accuracyof location data can be affected by adjustments to GPS satellites made by the UnitedStates government and is subject to change with the United States Department ofDefense civil GPS policy and the Federal Radionavigation Plan. Accuracy can also beaffected by poor satellite geometry. Availability and quality of GPS signals may beaffected by your location, buildings, natural obstacles, and weather conditions. GPSsignals may not be available inside buildings or underground and may be impairedby materials such as concrete and metal.GPS should not be used for precise location measurement, and you should neverrely solely on location data from the GPS receiver and cellular radio networks forpositioning or navigation.The trip meter has limited accuracy, and rounding errors may occur. Accuracy canalso be affected by availability and quality of GPS signals.Different positioning methods can be enabled or disabled in positioning settings.Check the satellite signal statusYour device does not have an internal GPS antenna. To use applications that requirea GPS connection, use a compatible GPS receiver (accessory sold separately).To check how many satellites the GPS receiver has found, and whether it is receivingsatellite signals, select Menu > Applications > Location and GPS data >Position > Options > Satellite status.If the GPS receiver has found satellites, a bar for eachsatellite is displayed in the satellite information view.The longer the bar, the stronger the satellite signal.When the GPS receiver has received enough data fromthe satellite signal to calculate your location, the barturns blue.Positioning© 2009 Nokia.
