What is the definition of AHRS?

Stands for attitude and heading reference system. An AHRS typically consists of either solid-state or micro-electromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers that provide attitude information for a vehicle (typically aircraft) based on roll (rotation about X-axis), pitch (rotation about Y-axis) and yaw (rotation about Z-axis).

Attitude and heading reference systems are sometimes referred to as MARG (magnetic, angular rate, and gravity).

AHRS are designed to replace traditional mechanical gyroscopic flight instruments.
