Description
STA8089G belongs to Teseo III family products.
STA8089G is a single die standalone positioning
receiver IC working on multiple constellations
(GPS/Galileo/GLONASS/BeiDou/QZSS).
The device is offered with a complete GNSS
firmware which performs all GNSS operations
including tracking, acquisition, navigation and
data output.
STA8089GBD can run also TESEO-DRAW the
STMicroelectronics dead reckoning firmware.
