TravellingNeed directions? Looking for a restaurant? Your device hasthe tools to get you where you want to be.Positioning (GPS)You can use applications such as GPS data to determine yourlocation, or measure distances and coordinates. Theseapplications require a GPS connection.About GPSThe coordinates in the GPS are expressed using theinternational WGS-84 coordinate system. The availability ofthe coordinates may vary by region.The Global Positioning System (GPS) is operated by thegovernment of the United States, which is solely responsiblefor its accuracy and maintenance. The accuracy of locationdata can be affected by adjustments to GPS satellites madeby the United States government and is subject to changewith the United States Department of Defense civil GPS policyand the Federal Radionavigation Plan. Accuracy can also beaffected by poor satellite geometry. Availability and qualityof GPS signals may be affected by your location, buildings,natural obstacles, and weather conditions. The GPS receivershould only be used outdoors to allow reception of GPSsignals.Any GPS should not be used for precise locationmeasurement, and you should never rely solely on locationdata from the GPS receiver and cellular radio networks forpositioning or navigation.The trip meter has limited accuracy, and rounding errors mayoccur. Accuracy can also be affected by availability and qualityof GPS signals.Different positioning methods can be enabled or disabled inpositioning settings.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 data overa packet data connection, which assists in calculating thecoordinates of your current location when your device isreceiving signals from satellites.When you activate A-GPS, your device receives useful satelliteinformation from an assistance data server over the cellularnetwork. With the help of assisted data, your device canobtain the GPS position faster.© 2009 Nokia. All rights reserved.76
