WebMay 1, 2024 · A response model by Nomoto et al. ( 1957) assumes the rigid-body movement, where a ship’s heading change is related to the rudder angle. It is also known as the KT model widely used for ship autopilot (Tomera 2010 ). WebAn attitude and heading reference system (AHRS) uses an inertial measurement unit (IMU) consisting of microelectromechanical system (MEMS) inertial sensors to measure the angular rate, acceleration, and Earth's magnetic field. These measurements can then be used to derive an estimate of the object's attitude. System Contributions
