1. Introduction
The GV75 is a compact waterproof GPS tracker designed for a wide variety of vehicle tracking
applications. It has multiple I/O interfaces that can be used for monitoring or controlling external
devices. Its built-in GPS receiver has superior sensitivity and fast time to first fix. Its quad band
GPRS/GSM subsystem supports 850/900/1800/1900 MHz allowing the GV75'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 extends battery life through sophisticated power
management algorithms. 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, low battery and
scheduled GPS position.
