The Teseo-LIV3R is a ROM-based GNSS module that simultaneously tracks GPS, Glonass, Beidou, and QZSS constellations, with Satellite-Based Augmentation System (S-BAS). It has a tracking sensitivity of -163 dBm and fast time-to-first-fix of less than one second that ensures excellent accuracy to within 1.5 meters (50% Circular Error Probability). This 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. The module also supports real-time assisted GNSS with free server access ensuring uninterrupted positioning data for dependable navigation.

The Teseo-LIV3R is FCC certified and is supported by the STM32 Open Development Environment. It is available in a compact package that measures 9.7 x 10.1 mm and is ideal for many, especially IoT applications, such as insurance, goods tracking, drones, tolling, anti-theft systems, people and pet location, vehicle tracking, emergency calls, fleet management, vehicle sharing, diagnostics, and public transportation. The module is easy to use and responds to proprietary National Marine Electronics Association (NMEA) commands.
