Positioning (GPS)You can use applications such as GPS data to determineyour location, or measure distances and coordinates.These applications require a GPS connection.About GPSThe 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. GPS signals may not be available insidebuildings or underground and may be impaired bymaterials such as concrete and metal.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.The trip meter has limited accuracy, and roundingerrors may occur. Accuracy can also be affected byavailability and quality of GPS signals.Different positioning methods can be enabled ordisabled in positioning settings.Assisted GPS (A-GPS)Your device also supports assisted GPS (A-GPS).A-GPS is requires network support.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 > GPS data and Options >38 Positioning (GPS)CyanCyan MagentaMagenta YellowYellow BlackBlackCyanCyan MagentaMagenta YellowYellow BlackBlack
