    M684 is a new generation of full constellation, multi-frequency RTK + IMU inertial navigation module independently developed by EYESTAR. The module has built-in high-precision gyroscope and accelerometer, and adopts a complete GNSS/INS integrated navigation algorithm engine to ensure that it can provide high continuity, high integrity and high frequency dynamic positioning results in the environment of GNSS signal rejection or signal obstruction.
    Features
    • High precision, small size, ultra-low power consumption (as low as 50mW)
    • Based on the latest generation of 12nm process highly integrated SoC chip design, core RF, baseband, built-in ARM integrated design
    • Built-in perfect GNSS/INS integrated navigation algorithm engine
    • Support 100Hz data output, which can meet the needs of high-speed motion carriers such as aircraft, high-speed rail, and automobiles
    • BDS B1I/B2a、GPS L1/L5、GLONASS L1/L2、GALILEO E1I/E5a、QZSS L1/L5
