High-performance Navigation 2 axis MEMS Gyro
Introduction
The ER-2MG-182 two-axis navigation MEMS gyroscope is small in size, light in weight, simple in structure and has 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.
