              Application No. 09/099,963                                                                                


              current position of an automotive vehicle to a given destination.  Figure 1 of Ayanoglu                   
              illustrates a block diagram of a navigation system 10 including a global positioning                      
              system (GPS) receiver 26 for approximating the actual position of an automotive vehicle                   
              70 (Figure 2).   The navigation system 10 includes a microcontroller 22, and a cathode                    
              ray tube (CRT) 20 coupled to the microcontroller 22 adapted to display images for                         
              navigation of an automotive vehicle 70.  An input source 25, preferably in the                            
              configuration of a keyboard (not shown), is coupled to microcontroller 22 to enable                       
              driver input into the system 10 (e.g., to enable a driver to designate a destination while                
              viewing the CRT 20 or input a desired traveling route).  The system 10 further                            
              preferably includes a conventional CD-ROM (compact disc read only memory) 24                              
              coupled to the microcontroller 22.  The CD-ROM 24 is adapted to store various road                        
              map information classified in accordance with selected geographical regions.                              


                     The GPS receiver 26 is coupled to the microcontroller 22 and is adapted to                         
              receive positioning signals, via antenna 27, from GPS satellites 29, 31 and 33 so as to                   
              enable the approximation of the actual position of the automotive vehicle.  Preferably,                   
              the microcontroller 22 is coupled to both a direction sensor 28 for detecting the direction               
              of travel of the automotive vehicle, and a distance sensor 30 for measuring the traveling                 
              distance of the automotive vehicle to assist in the approximation of the actual position                  
              of the automotive vehicle.
