Due to the high cost of fossil-based energy, several
methods are proposed to reduce the usage of the energy in
logistics and fleet management to be even more. GPS tracking
system is a common approach to get vehicle location information
in real-time for fleet planning. We proposed a GPS tracking
system called Goo-Tracking that is composed of commodity
hardware, open source software and an easy-to-manage user
interface via a web server with Google Map or via Google Earth
software. The system includes a GPS/GPRS module to location
acquisition and message transmission, MMC to temporary store
location information, and an 8-bit AVR microcontroller. Our
system prototype is shown and tested on a trip from Bangkok to
Chonburi. It has shown great stability and also robust message
transfer protocol that most of locations are accurately acquired
and transmitted to the server in real-time.
