AVL GPS Tracker(JAVA), Cost Efficient

VT-850WS is a versatile and economical platform for mobile positioning applications. It integrates UniTraQ GPS module with Quad-band 850/900/1800/1900GSM/GPRS communication module and powerful microcontroller all onto a single board. It is enclosed in a solid casing for easy installation. VT-850WS provides reliable Real Time vehicle GPS positions anytime anywhere in the world, providing the correct position and status of vehicles from remote locations onto computer displayed maps. Benefits such as increased fleet efficiency, improved public and driver safety, better emergency response time, enhanced fleet control, and good public relations are all realized through the proper implementation of VT-850WS system.The VT-850WS system takes advantage of JAVA machine to transmit NMEA message to 24-hrs
Control Center by Packet-Switch for monitoring through either GPRS or SMS massage system. Control center sets command by sending commands for monitoring through GSM system or Internet access.
