1. Introduction
The GV300W is a compact GNSS 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 GNSS receiver has superior sensitivity and fast time to first fix.
Its triple band WCDMA subsystem supports UMTS/HSDPA 850 (Band V)/1900 (Band
II)/2100(Band I) MHz allowing the GV300W'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 driving behavior monitoring, motion detection and extended 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 GNSS position.
