The AHRS-2G is a high-performance strapdownattitude and heading reference system that determines absolute orientation (heading, pitch and roll) for any device on which it is mounted. Orientation is determined with high accuracy for both motionless and dynamic applications.
In order to determine orientation, it utilizes 3-axes each of precision accelerometers, magnetometers, and gyroscopes. Integration of gyroscopes' output provides high frequency, real-time measurement of the device rotation about all three rotational axes. Accelerometers and magnetometers measure absolute pitch, roll and magnetic azimuth at AHRS initial alignment as well as providing ongoing corrections to gyroscopes during operation.
