Description

STA8090WG belongs to Teseo III family products.

STA8090WG is a single die standalone

positioning receiver which embeds the new ST

GNSS positioning engine capable of receiving

signals from multiple satellite navigation systems,

including GPS, Galileo, Glonass, BeiDou QZSS.

The minimum BOM and small WLCSP package

make STA8090WG the ideal solution for low-cost

and small footprint products such hand-held

computers, cameras, data loggers, and sports

accessories.

The device is offered with a complete GNSS

firmware which performs all GNSS operations

including tracking, acquisition, navigation and

data output.
