SKG12MI-03U car integrated navigation module

SKG12MI-03U is a high-performance vehicle-mounted integrated navigation module, designed specifically for automotive navigation applications. It incorporates a high-performance multi-constellation GNSS receiver chip that supports GPS, BDS (BeiDou), GLONASS, Galileo, and QZSS, along with dual-frequency positioning (L1 + L5), 3-axis gyroscope, and 3-axis accelerometer.

Leveraging an online adaptive integrated navigation algorithm, the SKG12MI-03U delivers real-time, high-precision vehicle positioning, speed, and attitude information. Even in scenarios where GNSS signals are degraded or completely lost (such as in tunnels or underground parking), the SKG12MI-03U can independently maintain high-precision positioning and orientation using pure inertial navigation, without relying on odometer data.

The module also outputs total mileage directly, providing convenient distance measurement for navigation and fleet tracking applications.
