9-Axis Attitude Sensor Module

Supports dynamic attitude measurement
SCI serial communication
Automatic periodic transmission of attitude information
Professional calibration function with real-time transmission of calibration status

Product Introduction

The GMU080 nine-axis attitude reference system (AHRS) integrates a three-axis fluxgate sensor, a three-axis MEMS accelerometer, and a three-axis MEMS gyroscope to form a complete inertial measurement unit (IMU). This system achieves three-dimensional attitude calculation of the vehicle through multi-sensor data fusion. Its main functions include real-time heading, pitch, and roll angle measurement, dynamic attitude tracking, and outputting attitude parameters via a standard communication interface. The sensors are orthogonally configured; the fluxgate sensor provides geomagnetic field vector measurement, the accelerometer senses specific force information, and the gyroscope detects angular rate, collectively forming a high-precision attitude reference system.
