GL50 is a mini GNSS tracking device that allows GNSS and base station positioning. It features a 2200-day ultra-long standby time using an internal lithium manganese battery for power supply with an outstanding consumption control method. GL50 supports a flexible switch between the wake-up mode for reporting and the hibernation mode to realize deep dormancy. System integration is straightforward as complete documentation is provided for the full-featured @Track protocol. The integrated @Track interface protocol allows GL50 to communicate with a customer mobile phone via SMS or a backend server to transfer a wide variety of reports.
