The 3DM-GX4-15™ is a miniature high end industrial Inertial Measurement Unit (IMU), utilizing the highest performance MEMS sensor technology. It combines a triaxial accelerometer, triaxial gyro, temperature sensors, pressure altimeter and dual on-board processors running a sophisticated Adaptive Kalman Filter to provide excellent static and dynamic inclination estimates and inertial measurements. All of its features combine to make it the smallest and best performing IMU in its class.
