    ER-MNS-09 MEMS Triaxial North Seeker for Mining

    Based on three-axis integrated MEMS gyro and three-axis accelerometer, ER-MNS-09 north finder can complete the initial alignment, attitude holding functions, and real-time output of carrier attitude reference values.

    Angular rate and acceleration measurement function;
    Self-alignment function;
    Attitude tracking function;
    RS-422 serial communication.

    North seeking in logging tools/gyro tools;
    Pointing, steering and steering of advanced mining/drilling equipment;
    Initial alignment of weapon/drone launch system;
    Satellite antenna direction indication and target tracking system;
    Guidance and navigation of navigation-level MEMS weapon systems;
    Orientating and positioning in railway train system;
    Precision platform attitude measurement and control;
    Navigation-grade MEMS INS high-precision attitude and position measurement;
    North seeking positioning in land surveying/land mobile surveying and mapping systems.

    The coordinate axis definition of ER-MNS-09 north seeker is shown in Figure 1.
    The positive direction of the X-axis is along the direction of the system connector. When the system is installed through the four mounting flanges on the bottom, the Z-axis defines the upward direction. X, Y, and Z form a Cartesian orthogonal coordinate system.
    The system output pitch angle/inclination angle indicates: the angle between the positive direction of the Y-axis and the horizontal plane, upward is positive.
