Micro Vehicle Tracking Device


The unit is only for sale in Europe, Africa, and Asia.

The GV65 is a mini GNSS tracker designed for a wide variety of vehicle tracking applications. It has multiple digital/analog I/Os and includes a 1-wire interface used for driver ID and temperature monitoring. Its built-in GNSS subsystem supports GPS and GLONASS and has an optional external antenna allowing superior sensitivity and fast time to first fix. Its quad band GPRS/GSM subsystem supports 850/900/1800/1900 MHz allowing the GV65's location to be monitored in real time or periodically tracked by a backend server and mobile devices. Its built-in 3-axis accelerometer allows motion detection and sophisticated power management. System integration is straightforward as complete documentation is provided for the full featured @Track protocol. The @Track protocol supports a wide variety of reports including emergency, geo-fence boundary crossings, driving behavior, external power supply monitoring and scheduled GNSS position.
