1. 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 Dual-Band GSM frequencies
850/1900, its location can be monitored in real time or be 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 or 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 setup their tracking
systems based on the full-featured @Track protocol.
