3DM-GX5-AHRS Attitude & Heading Reference System
The 3DM-GX5-AHRS is an industrial-grade AHRS in a compact and lightweight package, delivering IMU outputs such as acceleration and angular rate as well as computed outputs including highly accurate attitude and heading estimates. The sensor utilizes advanced auto-adaptive Kalman Filter algorithms for superior performance even under highly dynamic conditions, and allows IMU and filtered outputs to be configured independently.
All units are individually calibrated and fully temperature-compensated for optimal performance. The rugged machined aluminium enclosure provides protection in demanding environments with high levels of shock and vibration.
