1. Introduction
The GMT200 is a water resistant GPS tracker designed for applications requiring low
current drain such as motorcycles and boats. 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 GMT200'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. Further reduction in current drain is achieved by
configuring alternative recharge schemes for the internal battery. It measures
70mm*46mm*17.5mm and weighs only 65g, allowing easier and more covert installation.
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, low battery and scheduled GPS
position.
