GPS/BDS/GLONASS Combination Navigation Module SKM-4DU

SKM-4DU provides real-time high-precision vehicle positioning, speed measurement and attitude measurement information. When the signal accuracy of the GNSS system is reduced or even the satellite signal is lost, the odometer information is not used.

Using pure inertial navigation technology, SKM-4DU can also perform high-precision positioning, speed measurement and attitude measurement on the vehicle carrier alone for a long time. The module can directly output the total mileage, which is convenient for customers to measure the mileage.
