Introduction

ER-MNS-06A Low cost MEMS north seeker for Heading machine

Introduction

ER-MNS-06A is an ultra-low-cost MEMS north seeker mainly used for tunnel boring machines. It adopts the latest MEMS gyro technology and is a precision measurement and orientation device that breaks through the traditional volume advantage. It has the characteristics of small size, light weight, and low power consumption.

The compact size and lightweight structure greatly reduce the requirements for installation space and can be seamlessly embedded in narrow space scenes. It is mainly used in mining engineering, underground tunneling, construction and other fields. It can be integrated in engineering machinery such as tunnel boring machines and mining equipment, as well as various fields that require orientation.

Different from traditional magnetic compasses, the north finder is completely unaffected by the geomagnetic field. It adopts three-axis MEMS gyroscope and three-axis MEMS plus meter strapdown inertial measurement technology. It does not require external reference signals to solve the carrier attitude and north azimuth. It can still maintain stable output in strong magnetic environments, high-latitude geomagnetic anomaly areas or electromagnetic pulse environments.
