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
Single-die, simultaneous quad-band (L1+L2+L5+E6) GNSS devices using ST’s proprietary phase-change memory with a single configurable firmware binary for multi-band reception up to quad band.
GNSS receiver ICs, offering on-chip, dual and triple (L1+L5 or L1+L2+L5), multi-constellation, carrier-phase tracking for higher accuracy and precise positioning and autonomous position, velocity and time (PVT) calculations on a single chip.
Tiny, dual-band, low-power GNSS module
Standalone GNSS-L1 receiver ICs with reduced power consumption, carrier-phase tracking for higher accuracy, and support for Read-only Memory (ROM).
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.
