STMicroelectronics offers first automotive, triple-band GNSS in a single chip

STMicroelectronics, a global semiconductor provider serving customers across the spectrum of electronics applications, has introduced a world-first, automotive satellite-navigation chip that delivers high-quality position data needed by advanced driving systems.

Joining ST’s Teseo V family, the STA8135GA is the first automotive-qualified, global navigation satellite system (GNSS) receiver to integrate a triple-band positioning measurement engine on-chip — in addition to standard multi-band, position-velocity time (PVT) and dead-reckoning.

Triple band has historically been used in professional applications such as surveying, mapping, and precision agriculture that demand millimeter accuracy with minimal reliance on correction data. Until now, it has only been available in chipsets or modules, which are typically larger and more expensive than ST’s single-chip solution.

STMicroelectronics’ new triple-band chip enables the receiver to efficiently acquire and track the largest number of satellites in multiple constellations simultaneously for superior performance in difficult conditions such as in urban canyons and under tree cover.

“The high precision and single-chip integration delivered by the STA8135GA satellite receiver enables the creation of reliable and affordable navigation systems that enable vehicles to be safer and more context aware,” said Luca Celant, GM, ADAS, ASIC and Audio Division, Automotive and Discrete Group, STMicroelectronics. “Our unique in-house design resources and processes for high-yield manufacturing are among the critical capabilities that have made this industry-first device possible.”

Bringing this capability to the automotive market in a compact and convenient package, the STA8135GA helps driver-assistance systems make accurate decisions about the road ahead. The multi-constellation receiver delivers raw information for the host system to run any precise-positioning algorithm, such as precise-point positioning and real-time kinematic.

The STA8135GA also enhances the performance of in-dash navigation systems, telematics equipment, smart antennas, and V2X communication systems, as well as marine navigation systems, drones, and other vehicles.
