Product overview
Description
The STA8100GA is part of the TeseoV family. The STA8100GA is a multiband multiconstellation positioning receiver IC able to manage all the GNSS constellations such as GPS, Galileo, Glonass, BeiDou, NAVIC (former IRNSS), and QZSS in the L1, L2, L5, and E6 frequency bands. The STA8100GA supports L2 and E6 baseband signal processing. The RF reception of the L2 and E6 signals requires an external front-end IC (STA5635A). The STA8100GAD comes with STMicroelectronics's dead reckoning firmware called TESEO-DRAW.
