ER-MNS-09 MEMS Triaxial North Seeker for Mining
Introduction
Based on three-axis integrated MEMS gyroscope and three-axis MEMS accelerometer, ER-MNS-09 north finder can complete the initial alignment, attitude holding functions, and real-time output of carrier attitude reference values.
Features
Angular rate and acceleration measurement function;
Self-alignment function;
Attitude tracking function;
RS-422 serial communication.
Applications
North seeking in logging tools/gyro tools;
Pointing, steering and guiding 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.
