3DM-GX5-AHRS

The 3DM-GX5-AHRS is the industry's most proven high performance industrial AHRS.

It features a fully calibrated and temperature compensated triaxial accelerometer, gyroscope, and magnetometer to achieve the optimum combination of measurement qualities under all dynamic conditions. The dual on-board processors run an exclusive Auto-Adaptive Extended Kalman Filter (EKF) for outstanding dynamic attitude estimates, making it ideal for a wide range of applications, including platform stabilization, robotics, and vehicle health and usage monitoring.
