Overview
The STA8090FGBDTR is a highly integrated GNSS (Global Navigation Satellite System) receiver IC from STMicroelectronics, belonging to the Teseo III family of products. This single-die standalone positioning receiver supports multiple constellations including GPS, Galileo, GLONASS, BeiDou, and QZSS. It is designed to provide a compact and cost-effective solution for various applications, offering a high level of integration with embedded RF Front-End and low noise amplifier. The device is backward compatible and can run STMicroelectronics' dead reckoning firmware, TESEO-DRAW, enhancing its navigation capabilities.
