ER-MNS-09 MEMS North Seeker for Mining

Introduction
With the rapid development of science and technology, MEMS North Seeker is increasingly widely used in the fields of oil and mining, injecting new vitality into this traditional industry. This is a high-performance product specially designed for oil drilling, mining and other fields. Based on three-axis 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.Using the latest three-axis MEMS gyroscope, three-axis MEMS plus strapdown inertial measurement technology;
2.Subvert the size of the traditional gyroscope tool, small to the extreme, only 30mm in diameter, 120mm in length;
3.Solid-state design, anti-impact, anti-vibration ability is excellent;
4.30s fast alignment, azimuth accuracy 1°; 90s accurate alignment, azimuth accuracy 0.5°;
5.Not affected by magnetic field;
6.With self-seeking north function;
7.5 ~ 125°C full temperature scale compensation, adapt to extreme environment.

Applications
1) North seeking in logging tools/gyros;
2) Pointing, steering and steering of advanced mining/drilling equipment;
3) Initial alignment /drone launch system;
4) Satellite antenna direction indication and target tracking system;
5) Guidance and navigation of navigation-level MEMS systems;
6) Orientating and positioning of railway train systems;
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.
