GV300VC User Manual
1. Introduction
The GV300VC is a compact 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 dual band CDMA2000-1x
allows the GV300VC'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 behaviour 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 behaviour, low battery and scheduled GPS position.
