Abstract: A standout amongst the most difficult issues for Marine Satellite Tracking Antennas (MSTA) is to gauge the radio wire disposition which influenced by the ship movement, particularly the ship vibration and rotational movements brought on by sea waves. To conquer this issue an Attitude Heading and Reference System (AHRS) for MSTA displayed in this study including equipment engineering, estimation calculation and alignment. The material structure outlined with the end goal that it expands the vibration resistance of AHRS and estimation precision. Other than Multiplicative Extended Kalman Filter (MEKF) for typical working conditions, a disposition estimator in light of Virtual Horizontal Reference (VHR) is presented for circumstances of accelerometer glitch or where the ship is experiencing wave stuns in high ocean states. The execution of the outlined AHRS for MSTA evaluated through equipment tests utilizing a Stewart stage and a high-accuracy business AHRS.
