Assisted GPS (A-GPS) Your device also supports assisted GPS (A-GPS). A-GPS requires network support. Assisted GPS (A-GPS) is used to retrieve assistance data over a packet data connection, which assists in calculating the coordinates of your current location when your device is receiving signals from satellites. When you activate A-GPS, your device receives useful satellite information from an assistance data server over the cellular network. With the help of assisted data, your device can obtain the GPS position faster. Your device is preconfigured to use the Nokia A-GPS service, if no service provider-specific A-GPS settings are available. The assistance data is retrieved from the Nokia A-GPS service server only when needed. To disable the A-GPS service, select Menu > Applications > Location and Options > Positioning settings > Positioning methods > Assisted GPS > Disable. You must have an internet access point defined in the device to retrieve assistance data from the Nokia A-GPS service over a packet data connection. The access point for A-GPS can be defined in positioning settings. A wireless LAN (WLAN) access point cannot be used for this service. Only a packet data internet access point can be used. Your device asks you to select the internet access point when GPS is used for the first time. Hold your device correctly When using the GPS receiver, ensure you do not cover the antenna with your hand. Establishing a GPS connection may take from a couple of seconds to several minutes. Establishing a GPS connection in a vehicle may take longer. The GPS receiver draws its power from the device battery. Using the GPS receiver may drain the battery faster. Tips on creating a GPS connection Check satellite signal status To check how many satellites your device has found, and whether your device is receiving satellite signals, select Menu > Applications > Location and GPS data > Options > Satellite status. 80 © 2009 Nokia.
