Abstract: 본 발명은 차량 운행시 이동 통신 기지국에서 기지국 위치 신호를 송신토록 하고, 이 송신된 기지국 위치 신호를 차량에서 수신할 수 있도록 하여 운행 차량의 위치를 파악할 수 있도록 한 차량의 네비게이션 시스템에 관한 것으로, 
     본 발명은 우리 나라 전역에 중첩되어 설치되고, 기지국 위치 신호를 송신하는 이동 통신 기지국과; 상기 이동 통신 기지국에서 송신되는 기지국 위치 신호를 수신하고 수신된 위치 신호로 차량의 위치를 파악하는 수신장치가 구비된 차량으로 구성하되, 상기 수신장치는 다수개의 이동 통신 기지국으로 수신되는 기지국 위치 신호를 수신하는 수신기와; 상기 수신기에서 수신된 기지국 위치 신호에 대하여 기지국으로부터 송신 전파의 도착 시간을 연산하고, 이 연산된 시간으로 기지국과 거리를 환산하며 이 환산된 거리로 기 저장된 지도 및 정보부로부터 차량의 현위치를 파악하는 제어기와; 상기 제어기에서 파악된 차량의 현위치를 인식하는 인식수단으로 구성된다.
