Positioning (GPS)You can use applications such as GPS data to find outyour location, or measure distances and coordinates.These applications require a GPS connection.About GPSThe coordinates in the GPS are expressed in thedegrees and decimal degrees format using theinternational WGS-84 coordinate system.The Global Positioning System (GPS) is operated by thegovernment of the United States, which is solelyresponsible for its accuracy and maintenance. Theaccuracy of location data can be affected byadjustments to GPS satellites made by the UnitedStates government and is subject to change with theUnited States Department of Defense civil GPS policyand the Federal Radionavigation Plan. Accuracy canalso be affected by poor satellite geometry. Availabilityand quality of GPS signals may be affected by yourlocation, buildings, natural obstacles, and weatherconditions. The GPS receiver should only be usedoutdoors to allow reception of GPS signals.Any GPS should not be used for precise locationmeasurement, and you should never rely solely onlocation data from the GPS receiver and cellular radionetworks for positioning or navigation.To enable or disable different positioning methods,select Menu > Applications > Location andPositioning > Positioning methods.Assisted GPS (A-GPS)Your device also supports assisted GPS (A-GPS).A-GPS is a network service.Assisted GPS (A-GPS) is used to retrieve assistance dataover a packet data connection, which assists incalculating the coordinates of your current locationwhen your device is receiving signals from satellites.When you activate A-GPS, your device receives usefulsatellite information from an assistance data serverover the cellular network. With the help of assisteddata, your device can obtain the GPS position faster.Your device is preconfigured to use the Nokia A-GPSservice, if no service provider-specific A-GPS settingsare available. The assistance data is retrieved from theNokia A-GPS service server only when needed.To disable the A-GPS service, select Menu >Applications > Location and Options >80 Positioning (GPS)
