Attitude and Heading Reference Systems are enhanced, high-performance strapdown systems, that determine absolute orientation (Heading, Pitch and Roll) and Heave for any device on which they are mounted. Orientation is determined with high accuracy for both motionless and dynamic applications.
AHRS utilize 3-axes each of precision accelerometers, magnetometers and gyroscopes to provide accurate Heave, Heading and Attitude of the device under measure. Integration of gyroscopes’ output provides high frequency, real-time measurement of the device rotation about all three rotational axes. Accelerometers and Fluxgate magnetometer measure absolute Pitch, Roll and magnetic Azimuth at AHRS initial alignment as well as providing ongoing corrections to gyroscopes during operation.
AHRS applies state-of-the-art algorithms for different dynamic motions of Vessels, Ships, ROV, UUV, Robots, UAV, UGV, AGV, Gimbals and Antennas.
