Overview
The STA8090WG, part of the Teseo III family from STMicroelectronics, is a single die standalone positioning receiver. It integrates the new ST GNSS positioning engine, capable of receiving signals from multiple satellite navigation systems including GPS, Galileo, GLONASS, BeiDou, and QZSS. This device is designed for low-cost and small footprint applications such as hand-held computers, cameras, data loggers, and sports accessories. The STA8090WG comes with a complete GNSS firmware that handles all GNSS operations, including tracking, acquisition, navigation, and data output.
