With rapid development of the science technology, the GPS technology used in the ground mobile target track localization has widely applied. As the intelligence transmission method of track localization and long-distance monitoring to GPS, the wireless communication technology is the key to realize its function. The popularization of GSM has provided the reliable safeguard to the GPS technology widespread application, specially the SMS which provided by the GSM network causes the intelligence transmission conveniently to be quick, causes the operating cost of the GPS system largely scale drop. As GPS application carrier, GIS has developed the widespread application space by its accurate and reliable data, diverse information output. With these kinds of technical used, coordinate the database management system, the internet network communication, the web server, may construct precisely, real -time, inexpensive route guidance system, carrying on the effective management, the communication, the issue to the data.
