This paper proposes a real-time ambulance/vehicle tracking system using a global positioning system (GPS) technology module to receive the location of the vehicle, to forward into microcontroller and to connect internet by a general packet radio service (GPRS) technology for displaying a real time on the website map developed by Google Map which allows inspection of vehicles at all times. There are 3 parts of this project. The first part is a program developed in C language for controlling the hardware. Employing PHP and AJAX language will be developed for the Google Map API to help a map construction on the website. The second part is the hardware, there are the GPS and GPRS modules, the GPS module will locate the vehicles via the satellite, and the GPRS module will assemble all data and send it to the website by the microcontroller. The final part is the interface using RS232 for connecting between the GPS and GPRS modules. With the Google Map on a real-time website, vehicles can be monitored and located very effectively. This includes paths and/or vehicles directions. However, the small error is at approximately 5 meters in the wrong location due to the limitation of hardware and the ratio of map reference.
