International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, NevadaThis paper presents the design and implementation of a large fleet management system, which is a true convergence solution of GPS, web-based GIS, GSM, GPRS and Internet technologies. The Short Message Service of the GSM is used to substitute the GPRS where GPRS is not available. A protocol stack including TCP/IP and PPP is implemented in vehicle unit to transmit data via Internet. A communication gateway is designed to distribute the location and control messages. The system tests confirm that the proposed scheme can perform a reliable management service for large fleets at low operating and maintaining costs.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
