Description
STA8100GA is part of the Teseo V family.
STA8100GA is a multi-band multi-constellation positioning receiver IC able to manage all the GNSS
constellations such as GPS, Galileo, Glonass, BeiDou, NAVIC (former IRNSS) and QZSS, in L1, L2, L5
and E6 frequency bands. Security feature (enabled only for STA8100GAS) is implemented in a dedicated
sub-system, embedding cryptographic HW accelerator with protected access.
STA8100GAD and STA8100GADS are offered with STMicroelectronics dead reckoning firmware called
TESEO-DRAW.
