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.
