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.
