Abstract: A global positioning system (GPS) having instant notification of vehicle status function includes a GPS satellite signal-receiver module (11), a satellite signal-receiving antenna (12), a checking signal processing circuit (20) and a wireless communication module (30). The GPS satellite signal-receiver module (11) acquires an abnormal status of vehicle message from the checking signal processing circuit (20), and via the satellite signal-receiving antenna (12) receives vehicle position data. After processing, the wireless communication module (30) sends the data to a remote host (62) to provide the instant notification of vehicle status. Therefore, the GPS having instant notification of vehicle status function can effectively simplify a module of vehicle theft and security system circuits and components, so as to reduce cost.
