The GNSS module provides odometer functionality with three trip counters and reached-distance alert, along with geofencing capabilities with up to eight configurable circles and crossing-circles alarm. Support for real-time assisted GNSS with free server access ensures uninterrupted positioning data for dependable navigation.
Simultaneous tracking of GPS, Glonass, Beidou, and QZSS constellations, with Satellite-Based Augmentation System (S-BAS) and RTCM V3.1 differential positioning ensures accuracy to within 1.5 meters (50% CEP. Tracking sensitivity of -163dBm and time-to-first-fix faster than one second ensure high performance for demanding applications. The module has been designed to be easy to use and responds to proprietary NMEA commands.
With scalable power consumption according to accuracy, average current, and frequency of fixes, a sub-15µA standby mode with RTC backup, and support for multiple low-power modes, the Teseo-LIV3R is suitable for battery-sensitive applications. The low-power modes include continuous-fix with adaptive and power-saving cycled modes, periodic-fix with GPS only, and fix-on-demand with the device in permanent standby.
The module is FCC certified and is supported by the STM32 Open Development Environment. STM32 applications for advanced geolocation, smart tracking, and server-assisted GNSS are available, and designers will benefit from the EVB-LIV3x evaluation board and X-NUCLEO-GNSS1A1 expansion board. The Teseo Suite PC tool helps easily configure settings and fine-tune performance.
