Teseo-LIV3FL GNSS module for low-power industrial and IoT positioning applications


The best accuracy in a tiny form factor

An easy-to-use, standalone Global Navigation Satellite System (GNSS) module, the Teseo-LIV3FL sustains power supply domains as low as 1.8V in addition to the standard 3.3V. It’s able to provide measurement data (carrier phase) supporting RTK/PPP client algorithms for precise positioning applications. Additional features include: 7-day Autonomous Assisted GNSS, Predictive Assisted GNSS and Real-Time Assisted GNSS. A complete development environment ecosystem is available.

Key features

  • Simultaneous multiconstellation positioning
  • -163 dBm tracking sensitivity
  • 1.5 m CEP position accuracy
  • Power supply voltages: 1.8 or 3.3 V
  • 8 μA standby current and 65 mW tracking power consumption
  • Tiny LCC 18-pin package (9.7 x 10.1 mm)
  • Operating temperature (from -40° to 85 °C)
  • Measurement data (carrier phase)
