TAU2202A is an automotive-grade GNSS module with dead reckoning, which is based on the Allystar CYNOSURE III SoC chips. It supports GPS, BDS, Galileo, and QZSS satellite signals. Combining GNSS positioning and inertial navigation technology makes TAU2202A output positioning data in the environments where GNSS signal quality is poor or even lost (such as tunnels, underground parking, etc.), and provide continuous and accurate positioning for navigation applications.

TAU2202A integrates a 3-axis accelerometer and a 3-axis gyroscope, while supporting other sensor access for multi-source information fusion to achieve higher positioning accuracy. Thanks to its excellent positioning performance in a harsh environment, TAU2202A is able to adapt to environment such as high temperature and strong electromagnetic interference in the vehicle to meet the application requirements of automotive manufacturers.
