What Is AHRS?

May 04, 2020

AHRS refers to the attitude and attitude reference system. It includes multiple axial sensors that can provide the aircraft with heading, roll, and roll information. Such systems are used to provide accurate and reliable attitude and navigation information for the aircraft. The heading reference system includes a MEMS-based three-axis gyroscope, accelerometer, and magnetometer. The difference between the heading reference system and the inertial measurement unit IMU is that the heading reference system (AHRS) contains an embedded attitude data solution unit and heading information. The inertial measurement unit (IMU) only provides sensor data and does not provide accurate Reliable attitude data function. The heading solution unit used for multi-sensor data fusion in the commonly used heading reference system (AHRS) is a Kalman filter.
