Introduction

ER-MNS-09 Directional Module for MEMS Directional Drilling/Drilling Directional Instrument

Introduction
ER-MNS-09 is a MEMS gyro directional module with a special-shaped cylindrical design. It uses a high-precision MEMS gyroscope that can find the north by itself. It determines the geographic true north direction by measuring the earth's rotation component. It does not rely on the geomagnetic field and can work stably in underground mines, metal pipelines or strong electromagnetic environments.

It can realize azimuth measurement, real-time output of the carrier's attitude reference value and attitude holding function. It has strong anti-shock and vibration capabilities, small size and light weight, and low power consumption. It is the most ideal equipment in the fields of mining, geophysical exploration, directional drilling, etc.

Features
1.Adopt the latest MEMS gyro technology, cylindrical design, its diameter is reduced to 30mm, length is 120mm, can be easily embedded in the narrow space at the front of the drilling equipment (such as the probe);
2.Adopt the latest three-axis MEMS gyro, three-axis MEMS accelerometerr strapdown inertial measurement technology;
3.Full solid-state design, built-in inner platform, excellent impact and vibration resistance, and resistant to harsh environments;
4.30s fast alignment, azimuth accuracy 1°, 90s precise alignment, azimuth accuracy 0.5°
5.With self-seeking north function, not affected by magnetic field.

Applications
1.Orientation and attitude measurement of advanced mining/drilling equipment;
2.Direction and trajectory control of non-excavation underground hidden engineering pipeline tracking and mapping;
3.Pipeline laying through and across operations in HDD;
4.Provide reference direction for total station and pointing instrument in tunnel construction;
5.Find north positioning in land surveying/land mobile mapping system.
