STMicroelectronics Monolithic Tri-Frequency Satellite Navigation Receiver Improves Vehicle Positioning Accuracy

     ST has launched the world's first automotive satellite navigation chip capable of providing high-quality location data for automotive advanced driving systems. As a new member of STMicroelectronics' Teseo V product family, the STA8135GA is the world's first automotive-grade GNSS (Global Navigation Satellite System) receiver chip that integrates a tri-frequency position measurement engine on-chip, and also integrates a standard multi-frequency position-velocity-time (PVT) and dead reckoning functions. And in a 7mm x 11mm x 1.2mm QFN package,

     Tri-frequency position measurement has historically been used in professional-grade equipment that requires millimeter-level positioning accuracy and basically does not require correction data, such as surveying and mapping instruments and precision agricultural equipment. Previously, the only tri-band solutions on the market were chipsets or modules, which were larger in size and higher in price compared to ST's single-chip solutions. Tri-band receivers capture and track the largest number of satellites in a technology that effectively captures and tracks multiple navigation constellation satellites simultaneously, enabling superior positioning performance in harsh environments such as urban canyons and tree cover Accuracy.

     Introducing tri-band receivers to the automotive market in a compact, easy-to-integrate package, the STA8135GA helps driver assistance systems make accurate judgments about the road ahead. This multi-constellation receiver is responsible for providing raw position information to the main control system, which runs precision positioning algorithms such as PPP/RTK (Precise Point Positioning/Real Time Motion). In addition, the STA8135GA can enhance the performance of other applications including in-vehicle navigation systems, telematics devices, smart antennas and V2X communication systems, marine navigation systems, drones and other vehicles.

     "The STA8135GA satellite receiver's high measurement accuracy and monolithic integration allow developers to design reliable, An economical navigation system that makes the car safer and more environment-aware. Our unique in-house design resources and mass-manufacturing technology are one of the elements of this industry-first product.”
