Allystar TAU1202 GNSS module
TAU1202 GNSS module
TAU1202 is a high-performance dual-frequency GNSS positioning module, which is based on the state of the art CYNOSURE III architecture. It supports GPS, BeiDou, GLONASS, Galileo, NavIC, QZSS and SBAS (WAAS, EGNOS, GAGAN and MSAS).
TAU1202 integrates efficient power management architecture, while providing high precision, high sensitivity and low power GNSS solutions which make it suitable for navigation applications on automotive and consumer electronics, as well as fleet management.
