Allystar TAU1308 GNSS module
TAU1308 GNSS module
TAU1308 is developed on the base of CYNOSURE III SoC chip. It is a positioning system that combines GPS, BeiDou, GLONASS, Galileo, and QZSS to provide a high precision positioning and navigation solution. With built-in single-band RTK engine, TAU1308 can achieve centimeter-level position accuracy, which makes it suitable for the industrial and consumer fields.
