Introduction
The AVT20 is a compact GNSS tracker designed for a wide variety of vehicle tracking applications. It has multiple I/O interfaces that can be used for monitoring or controlling external devices.
Its built-in GNSS receiver has superior sensitivity and fast time to first fix. Seven-band LTE-FDD in Europe and GSM/GPRS 850/900/1800/1900 MHz allow the AVT20's location to be monitored in real time or periodically tracked by a backend server and mobile devices.
The built-in 6-axis accelerometer and gyroscope support driving behaviour monitoring and motion detection.
