You must have an internet access point defined in thedevice to retrieve assistance data from the Nokia A-GPSservice over a packet data connection. The access point forA-GPS can be defined in positioning settings. A wirelessLAN (WLAN) access point cannot be used for this service.Only a packet data internet access point can be used. Yourdevice asks you to select the internet access point whenGPS is used for the first time.Hold your device correctlyThe GPS receiver is located on the back of the device. Whenusing the receiver, make sure that you do not cover theantenna with your hand.Establishing a GPS connection may take from acouple of seconds to several minutes.Establishing a GPS connection in a vehicle maytake longer.The GPS receiver draws its power from thedevice battery. Using the GPS receiver maydrain the battery faster.Tips on creating a GPSconnectionCheck satellite signal statusTo check how many satellites your device has found, andwhether your device is receiving satellite signals, selectMenu > Applications > GPS and GPS data > Options >Satellite status.If your device has foundsatellites, a bar for each satelliteis shown in the satellite infoview. The longer the bar, thestronger the satellite signal.When your device has receivedenough data from the satellite signal to calculate yourlocation, the bar colour changes.To view the positions of found satellites, select Chg.view.Initially your device must receive signals from at least foursatellites to be able to calculate your location. When theinitial calculation has been made, it may be possible tocontinue calculating your location with three satellites.However, the accuracy is generally better when moresatellites are found.If no satellite signal can be found, consider the following:• If you are indoors, go outdoors to receive a bettersignal.• If you are outdoors, move to a more open space.• Ensure that your hand does not cover the GPS antennaof your device.• If the weather conditions are bad, the signal strengthmay be affected.• Some vehicles have tinted (athermic) windows, whichmay block the satellite signals.57 Travelling2009-11-09 15:1:46
