T3GALAXY Tracker



The water resistant GALAXY is a powerful GNSS locator designed for lone worker, vehicle, parcel or asset tracking applications.

The thumb sized button makes this device ideal for applications requiring rapid notification of emergency alert or regular setting of geo-fences based on current location.

Galaxy GPS

Its built-in GNSS receiver supports GPS and GLONASS and has superior sensitivity and fast time to first fix. Its quad band GPRS/GSM subsystem supports 850/900/1800/1900 MHz allowing the GL300’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.
