Overview
The Teseo-LIV3FL module, produced by STMicroelectronics, is a compact and highly efficient global navigation satellite system (GNSS) standalone module. It integrates the Teseo III single die standalone positioning receiver IC, which supports multiple constellations including GPS, Galileo, GLONASS, BeiDou, and QZSS. This module is designed to offer superior accuracy and robustness, making it accessible for a wide range of applications. The embedded firmware and complete evaluation environment significantly reduce development time. The module's tiny size (9.7 x 10.1 x 2.3 mm) and low power consumption make it ideal for various use cases such as goods tracking, drones, tolling, anti-theft systems, people and pet location, vehicle tracking, emergency calls, fleet management, and public transportation.
