GNSS ICs & modules

ST's Teseo family of global navigation satellite system (GNSS) integrated circuits (ICs) and modules provide high-accuracy positioning capabilities. These standalone ICs and modules support up to quad-band operation and are compatible with multiple global navigation constellations: BeiDou, Galileo, GLONASS, GPS, Navic, and QZSS.

GNSS IC and module types

In addition to single-die standalone ICs, the Teseo family includes modules that integrate the GNSS chipset with necessary external components for a reduced Time To First Fix (TTFF):

  • Reduced design risk and simplified development, as the complex RF path design is already done
  • Embedded temperature-compensated crystal oscillator (TCXO), dedicated real-time clock (RTC), SAW filter, and RF front-end components
  • Larger, with fewer pins, and only require the connection of an appropriate antenna

GNSS modules offer a simpler and faster development process with reduced design complexity, while standalone GNSS ICs provide more flexibility for those with the necessary design expertise

TeseoVI family of GNSS positioning solutions

TeseoVI devices use ST’s proprietary phase-change memory which eliminates the need for an external memory:

  • Simplifies designs
  • Lowers BOM costs
  • Reduces possible supply chain issues

With the following benefits:

  • Single configurable firmware binary for multi-band reception up to quad band
  • Easier and less expensive to manage firmware versions and updates

All Teseo solutions offer a secure version leveraging an on-chip HSM to mitigate spoofing and jamming attacks in compliance with ISO/SAE 21434 automotive cybersecurity specifications.
