Have you ever heard the term AIS Alarm and wondered what it means? AIS, or Automatic Identification System, is a communication interface system based on International Maritime Organization-set standards that allows vessels of all sizes to broadcast their location, course and speed, as well as other data such as identification and weather. AIS works as a sophisticated radar system, displaying your vessel’s information to other vessels and shore stations. An AIS Alarm, however, is a user-defined alert that informs you when another vessel enters a pre-specified threat zone. It enables mariners to have the upper hand in navigating potential hazards in open sea or crowded waterways. With an AIS Alarm, you can be sure that your vessel and its crew are always one step ahead of any danger they may face while at sea.
