- Allystar
The TAU2102 is a compact, high-performance GNSS module powered by the Allystar CYNOSURE III SoC. It supports GPS, BDS (BeiDou), and QZSS satellite systems, offering reliable multi-constellation positioning.
A key feature of the TAU2102 is its integrated dead reckoning (DR) capability. By combining GNSS with inertial sensors (accelerometers and gyroscopes), it continues to provide accurate location data in areas where satellite signals are weak or unavailable, such as tunnels, underground parking, and urban canyons.
This module is ideal for automotive navigation, fleet tracking, and smart mobility applications requiring uninterrupted and precise positioning. With low power consumption and robust performance, the TAU2102 is well-suited for embedded systems in both consumer and industrial use cases.
