STMicroelectronics (ST), a global semiconductor company supporting diverse electronic applications and customers, has launched the world's first automotive-grade satellite navigation chip that provides high-quality position data required for advanced driving systems, delivering performance comparable to the highest-accuracy surveying and mapping equipment.

ST announced on the 22nd that it has launched the STA8135GA, the first automotive-grade GNSS (Global Navigation Satellite System) receiver in its Teseo V product family.

The STA8135GA integrates a triple-band positioning measurement engine on a single chip, in addition to standard multi-band PVT (Position-Velocity-Time) and Dead-Reckoning.

Triple-band has been used in specialized applications such as surveying, mapping, and precision agriculture that require millimeter-level accuracy while minimizing dependence on correction data.

Until now, triple-band functionality was typically available only in chipsets or modules that were larger and more expensive than ST's single-chip solutions. However, the receiver can now efficiently acquire and track the maximum number of satellites simultaneously from multiple satellite constellations, delivering exceptional performance even in challenging conditions such as densely built urban areas or under trees.

The STA8135GA brings this functionality to the automotive market in a compact and convenient package, enabling driver assistance systems to make accurate decisions regarding the road ahead.

This multi-satellite receiver delivers raw information enabling the host system to execute all precision positioning algorithms such as PPP/RTK (Precise Point Positioning/Real-Time Kinematic).

Additionally, the STA8135GA enhances performance in dashboard navigation systems, telematics equipment, smart antennas, V2X communication systems, as well as marine navigation systems, drones, and other vehicles.

Luca Celant, business line director of the Automotive and Discrete Group and Automotive Infotainment division at ST, stated, "The high-precision, single-chip integrated performance provided by the STA8135GA satellite receiver enables the implementation of a reliable and cost-effective navigation system that enhances vehicle safety and situational awareness. Key to creating this industry-first device are ST's unique design resources and process technology that deliver high production yield."

The STA8135GA is available in a 7mm x 11mm x 1.2mm QFN package. Samples are currently being supplied, with AEC-Q100 certification completion and production start scheduled for Q1 2022.
