Introduction

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.

Features

1) Angular rate and acceleration measurement function;
2) Self-alignment function;
3) Attitude tracking function;
4) RS-422 serial communication.

Applications

1) North seeking in logging tools/gyros;
2) Pointing, steering and steering of advanced mining/drilling equipment;
3) Initial alignment of weapon/drone launch system;
4) Satellite antenna direction indication and target tracking system;
5) Guidance and navigation of navigation-level MEMS weapon systems;
6) Orientating and positioning in railway train system;
7) Precision platform attitude measurement and control;
8) Navigation-grade MEMS INS high-precision attitude and position measurement;
9) 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.
