STMicroelectronics Teseo-LIV3FL Tiny Low Power GNSS Module

STMicroelectronics Teseo-LIV3FL Tiny Low Power GNSS Module is a standalone global navigation satellite system (GNSS) module. The Teseo-LIV3FL embeds the Teseo III single die standalone positioning receiver IC while working simultaneously on multiple constellations (GPS/Galileo/Glonass/BeiDou/QZSS). The device saves development time with embedded firmware and a complete evaluation environment. The proven accuracy and robustness of the Teseo chips, compactness and this solution’s economy make it ideal for various applications. These applications include 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 STM Teseo-LIV3FL Tiny Low Power GNSS Module offers superior accuracy via the integrated temperature, compensated crystal oscillator (TCXO), and a reduced time to first fix (TTFF) thanks to its dedicated real-time clock (RTC) oscillator. The device also provides the autonomous assisted GNSS able to predict satellite data based on previous observation of a satellite.

The Teseo-LIV3FL is available in a 9.7mm x 10.1mm tiny package with a temperature operating range from -40°C to 85°C.
