Introduction

STA8088EXG is a single die standalone positioning receiver IC working on multiple constellations (GPS/Galileo/Glonass/QZSS). By combining the ARM946 microcontroller core with the large number of peripherals/ interfaces, STA8088EXG provides a highly-flexible and cost effective solution for hand-held and telematic applications. The device is the ideal solution for sensor-based and sensor-less ST Dead Reckoning technologies which enhance positioning accuracy even in areas without GNsS signals, like tunnels and indoor parking.
