Over 12 Years of Experience in GPS Tracking


Multi-Function Mini Asset Tracker
The GL300 advanced asset tracker is a GNSS locator designed for multiple applications including employee safety, vehicle tracking, and other asset tracking.  The tracker includes a thumb-sized button designed for activities requiring fast notification of a panic situation or when the user needs to set repeated geo-fencing boundaries based on continuously changing locations.

The GL300 is water resistant, and its GNSS receiver provides both GPS and GLONASS capabilities along with faster times to first fix and increased sensitivity.  Quad band GPRS/GSM and 850/900/1800/1900 MHz capabilities support real time tracking or periodic location alerts using a backend server and mobile devices.  Motion detection through a 3-axis accelerometer extends battery life.  The GL300 supports multiple reporting options including geo-fencing, low battery alert, and scheduled GNSS location alerts.
