STA8088EXGA

射频接收器 High Flexible GPS/Galileo/Glonass/QZSS Receiver with powerful processing ARM9

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.
