STMicroelectronics Teseo-LIV3F Global Navigation Satellite System (GNSS) Module

Designed for top performance, taking up minimal space

The STMicroelectronics Teseo-LIV3F is a standalone Global Navigation Satellite System (GNSS) module that embeds TeseoIII single die standalone positioning receiver ICs, working simultaneously on multiple constellations (GPS/Galileo/Glonass/BeiDou/QZSS).

The Teseo-LIV3F brings the proven accuracy and robustness of Teseo chips to everyone involved in embedded firmware projects and complete evaluation environments to save crucial development time. The compactness and cost-effectiveness of LIV3F make it ideal for several applications, such as:

  • Insurance
  • Goods tracking
  • Drones
  • Tolling
  • Anti-theft systems
  • People and pet location
  • Vehicle tracking
  • Emergency calls
  • Fleet management
  • Vehicle sharing
  • Diagnostics
  • Public transportation


Within its 9.7x10.1 mm tiny size, the STMicroelectronics Teseo-LIV3F is offering superior accuracy thanks to the on-board 26 MHz Temperature Compensated Crystal Oscillator (TCXO) and a reduced Time To First Fix (TTFF) relating to its dedicated 32 KHz Real Time Clock (RTC) oscillator. The Teseo-LIV3F by STMicroelectronics features a temperature operating range from -40°C to 85°C.

Thanks to the embedded 16 Mbit flash, Teseo-LIV3F modules offer many extra functionalities such as data logging, 7 days autonomous assisted GNSS, FW reconfigurability as well as FW upgrades.

Teseo-LIV3F also provides Autonomous Assisted GNSS, able to predict satellite data based on previous satellite observations.

Optimize time to market with the Teseo-LIV3F module, a certified solution which optimizes the time to market of the final applications.
