217.81.145.219 (talk) added MARG acronym (which is relevant but also no place to put that anywhere else, too, as the MARG lemma is being squatted by an Indian Corporation (advert) and no disambig page) |

An attitude heading reference system consists of sensors on three axes that provide heading, attitude and yaw information for aircraft. They are designed to replace traditional mechanical gyroscopic flight instruments and provide superior reliability and accuracy.
AHRS consist of either solid-state or MEMS gyroscopes, accelerometers and magnetometers on all three axes. The key difference between an IMU and an AHRS is the addition of an on-board processing system in an AHRS which provides solved attitude and heading solutions versus an IMU which just delivers sensor data to an additional device that solves the attitude solution. In addition to attitude determination an AHRS may also form part of an INS (Inertial Navigation System)
A form of non-linear estimation such as an Extended Kalman filter is typically used to compute the solution from these multiple sources.[1]
