The water-resistant GL300 is a powerful GNSS locator designed for the lone worker, vehicle, pet, and 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. 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 for motion detection and extends battery life through sophisticated power management algorithms. The @Track protocol supports a wide variety of reports including emergency, geo-fence boundary crossings, low battery, and scheduled GNSS position.
