International ClassG01C 021/00Foreign Application Priority Data2000-03-03 JPAbstractA navigation terminal 2 loaded in a vehicle 1 is provided with a wireless communication device connectable to a movable communications network 3 and a present position detection device and instructs implementation of a predetermined navigation function. The gateway apparatus 4 connects the movable communications network 3 and the Internet 5 and implements protocol conversion and charging processing. A navigation server 6 acquires positional data of the vehicle 1 from the navigation terminal 2 via the Internet 5, discriminates map data to be a distribution object to the navigation terminal 2, and generates navigation information based on the instructed navigation function to provide it to the navigation terminal 2. A map server 7 reads map data discriminated as the distribution object from a map data base 8 accumulating map data and distributes them to the navigation terminal 2 via the Internet 5.Field of SearchAutomatic route guidance vehicleOn-board computer interact with a host computer Storage or planning of route information NAVIGATION Employing position determining equipment For use in a map data base system Means to improve accuracy of position or location With transmission of location-indicative information to or from a remote station Combined with telecommunication With storage device (i.e., map or database) VEHICLE POSITION INDICATION | |
