High-performance Navigation 3 axis MEMS Gyro
Introduction
The ER-3MG-182 three-axis Navigation MEMS gyroscope is small in size, light in weight, simple in structure and has good reliability. The 3-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.
Feature
Gyro bias instability: 0.03 deg/hr
Gyro bias stability (10s 1σ): <0.5 deg/hr
Gyro angle random walk: <0.025 °/√h
Application
Including agriculture, AUV, industrial equipment, robots, surveying, stabilization platforms, transportation, unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs).
