The 3DM-GX4 -25™ is a miniature high end industrial Attitude Heading and Reference System (AHRS), utilizing the highest performance MEMS sensor technology. It combines a triaxial accelerometer, triaxial gyro, triaxial magnetometer, temperature sensors, pressure altimeter and dual on-board processors running a sophisticated Adaptive Kalman Filter to provide excellent static and dynamic attitude estimates and inertial measurements. All of its features combine to make it the smallest and best performing AHRS in its class.
