The Inertial Labs Attitude and Heading Reference Systems, AHRS-II is the next generation of enhanced, highperformance strapdown systems 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.
The Inertial Labs AHRS-II-P utilizes Tactical-grade IMU: 3-axes each of precision
accelerometers & gyroscopes and Ultra High precision, gyro-compensated, embedded Fluxgate Compass to provide accurate Heading/Yaw, Pitch and Roll 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.
