Introduction

2-Axis North-Seeking MEMS Gyro

Introduction
The ER-2MG-181 two-axis north-seeking MEMS gyroscope is small in size, light in weight, and has a simple structure with good reliability. The dual-axis gyroscope has the greatest function of providing the angular velocity needed to determine the motion state of an object, and thus is also called a motion sensor.

Application
Construction machinery dip angle measurement, angle control, pylon operation monitoring, medical equipment angle control, satellite antenna star search, bridge, tall building, tower, dam monitoring and rock and soil monitoring, mining, attitude/heading reference system, integrated inertial navigation.
