STMicroelectronics has enlarged its GNSS product offering with the Teseo-LIV3R ROM-based module, providing a full GNSS algorithm capability for tracking and navigation devices.

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 is designed to ensure accuracy to within 1.5 m (50% CEP). Tracking sensitivity of -163 dBm and time-to-first-fix faster than 1 s ensure high performance for demanding applications. The module is easy to use and responds to NMEA commands.

With scalable power consumption according to accuracy, average current and frequency of fixes, a sub-15 µA standby mode with RTC backup and support for multiple low-power modes, the product 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, while the EVB-LIV3x evaluation board and X-NUCLEO-GNSS1A1 expansion board provide a head start with hardware. The Teseo Suite PC tool helps easily configure settings and fine-tune performance.
