GNSS Modules

Our standalone Global Navigation Satellite System (GNSS) modules are designed for top performance in a minimal space and are optimized for cost-sensitive applications without compromising on quality.

Cost-competitive, ST’s Teseo GNSS modules allow for easy integration and migration from existing product designs including trackers, telematics, portable, and tablets as well as marine and sports accessories.

Combining high positioning accuracy and indoor sensitivity with powerful processing capabilities, our tiny Teseo-LIV3x modules simultaneously support multiple global navigation systems including BeiDou, Galileo, GLONASS, GPS, and QZSS.

Addressing Industrial and Consumer applications, the Teseo-LIV3x family with its 9.7 x 10.1 mm compact size, offers superior accuracy thanks to its embedded temperature-compensated crystal oscillator (TCXO) and a reduced Time To First Fix (TTFF) using its dedicated real-time clock (RTC).

Addressing Dead-Reckoning and Automotive applications, the Teseo-VIC3x family with its 16 x 12.2 mm size, offers built-in sensor fusion able to guarantee PVT solution also in absence of satellites signal thanks to its on-board ST 6-axis sensor.


We provide a full development ecosystem including a complete standalone GNSS module evaluation and prototyping platform.

In addition to our powerful Teseo-Suite PC tool, we also provide STM32 function packs and expansion software as well as a flexible firmware solution that makes it easy to download new firmware and updates.
