Antenna alignment is a crucial factor in ensuring the AIS system transmits accurate positional data. AIS Class A and B systems are equipped with antennas that need proper alignment for effective communication and positioning. Regular service includes checking antenna angles, ensuring signal reception is unobstructed, and testing data transmission quality. Proper alignment and testing enhance the AIS system’s overall performance and ensure the vessel’s visibility on nearby radar systems, reducing collision risks. Timely service ensures compliance with SOLAS and other international maritime regulations.
