The Automatic Identification System (AIS) is a critical component for maritime safety, enabling vessels to track and be tracked by other ships. AIS system calibration and testing ensure that the system is transmitting accurate information regarding vessel location, speed, and course. Service includes verifying data accuracy, checking for signal interference, and ensuring compatibility with other onboard systems. Regular calibration helps prevent system errors, enhances collision avoidance, and ensures compliance with maritime safety standards, significantly improving the vessel’s operational safety.
