AIS Class A and Class B systems provide real-time data to identify and track vessels in the surrounding area. Regular maintenance includes testing the transponder, ensuring correct positioning data, and verifying communication links. Service tasks include updating software, replacing faulty components, and checking antenna alignment. Timely maintenance ensures that the AIS system operates at peak efficiency, improving navigation safety by reducing the risk of collisions. Properly maintained systems also ensure compliance with SOLAS regulations, enhancing vessel safety and providing peace of mind during voyages.
