In applications where stable attitude and heading are required—such as UAV stabilization, robotics, vehicles, and marine platforms—AHRS provides real-time orientation data you can actually use.

AHRS (Attitude and Heading Reference System)

By fusing data from gyroscopes, accelerometers, and often a magnetometer, an AHRS outputs roll, pitch, and yaw/heading with strong resistance to vibration and motion changes. It’s a practical choice when you need reliable orientation but don’t necessarily need full navigation (position/velocity) like an INS.
