Overview
The STA8089FGBD is a highly integrated single-chip standalone GNSS (Global Navigation Satellite System) receiver developed by STMicroelectronics. It belongs to the Teseo III family of products and is designed for positioning system applications. This device supports multiple satellite navigation systems, including GPS, Galileo, GLONASS, BeiDou, and QZSS. The STA8089FGBD is backward compatible with the STA8088FG, facilitating easy migration for customers. It comes with a complete GNSS firmware that handles all GNSS operations, including tracking, acquisition, navigation, and data output, without the need for external memories. Additionally, the STA8089FGBD can run STMicroelectronics' dead reckoning firmware, TESEO-DRAW.
