EnglishVehicle positioning systemn GPS (Global Positioning System)The positioning system uses communicationssatellites launched by the US Department ofDefense. Signals are received from three or moresatellites orbiting at 1 000 km altitude, andthe principle of triangulation is used to find theposition.By receiving GPS signals, this system canposition the vehicle within a margin of error of 0to 00 m.Time before the current position is foundWhen this system is used for the first time, or if ithas not been used for an extended period, it maytake as much as 5 minutes to find the currentposition. In normal conditions, at a locationwith good reception, positioning takes around minutes.Starting to move the vehicle immediately afterturning on the power causes it to take longer tofind the position, so the user is advised to remainparked in a location with good reception (with nobuildings or trees to block the signals from GPSsatellites) until the current position is found.n Locations where GPS signalreception is difficultReception may not be possible in locations suchas the following:l In tunnelsl Between tall buildingsl Under elevated roadsl Between treesWhat is a navigation system?n Map matchingThis function displays the current positionof your vehicle on the map. That position isacquired using GPS, gyro sensors, magneticsensors, etc.n Electric compassThis unit incorporates a magnetic sensor thatuses the slight geomagnetism in the earth todetect the bearing of the unit like a compass.Therefore, the position and bearing of yourvehicle can be corrected for display even inlocations where the GPS signal does not reach.* Vehicle positioning is not displayed perfectlyin locations where the GPS signal cannot bereceived.A navigation system marks a route to a destination or destinations on a map, guiding the user along theroute to the destination.26
