Product Introduction

The GMU406 is a high-performance inertial measurement unit (IMU) based on MEMS technology, designed specifically for precise platform attitude measurement and control. This device integrates an industrial-grade three-axis gyroscope and a three-axis accelerometer sensor, employing advanced dynamic attitude calculation algorithms to output high-precision attitude data in real time, including parameters such as three-dimensional attitude angles, heading angles, three-axis angular velocities, three-axis linear accelerations, and axial motion accelerations.

The product features excellent vibration suppression performance, maintaining stable attitude output even in complex vibration environments. A specially designed Z-axis angular velocity integration function provides accurate rotation angle counting output. As a core component of a new generation of intelligent attitude control systems, the GMU406 is widely used in automated control fields such as gimbal stabilization and precision operations, significantly improving system control accuracy and operational efficiency.
