Introduction
The GV300 is a powerful GPS locator designed for vehicle or asset tracking. It has superior
receiver sensitivity, fast TTFF (Time to First Fix) and supports quad band GSM frequencies
GSM850/GSM900/DCS/PCS. Its location can be monitored in real time or periodically tracked by
a backend server or other specified terminals. The GV300 has multiple input/output interfaces
that can be used for monitoring or controlling external devices. Based on the integrated @Track
protocol, the GV300 can communicate with a backend server through the GPRS/GSM network to
transfer reports of emergency, geo-fence boundary crossings, low backup battery and scheduled
GPS position as well as many other useful functions. Users can also use GV300 to monitor the
status of a vehicle and control the vehicle by its external relay output. System integrators can
easily set up their tracking systems based on the full-featured @Track protocol.
