With today’s Global Positioning System (GPS) availability and with Global System for Mobile Communication (GSM) technology enhancements and reliability, the use of vehicle tracking system becomes more useful and efficient. Stand-alone GPS receivers are able to determine location with high accuracy; these receivers can also transmit the position using integrated GSM modems enhancements. These features which take into consideration important factors regarding both GPS and data communication using General Packet Radio Service (GPRS) provided by GSM can be combined together to build an integrated web-based vehicle tracking system. This thesis explores the design and implementation of an integrated cost effective, easy to use web-based GPS-GPRS vehicle tracking system. The thesis describes a system implemented using two common technologies GPS and GSM where GPS is used to determine vehicle current position indicating the coordinates received from satellite such as latitude, longitude, and direction of travel with accuracy ranges from 2.5-20 meters, the precise Universal Time Coordinated (UTC) and speed can also be obtained with accuracy reaches up to 5nsec. This information is transmitted to a static IP address using GPRS and hence becomes available to be displayed on embedded Google Map. The web-based vehicle tracking system is designed and tested using quadband SIM908 development kit. The implemented system is easy to use and access restricted for authorized persons, besides to the large number of users the system interact with. Also the standardization and general rules followed through design and implementation makes the system expandable and scalable.
