Automatic Identification System (AIS) is a maritime technical standard developed by the International Maritime Organisation (IMO). 

AIS is a sophisticated radio technology which combines GPS, VHF and data processing technologies to enable the exchange of relevant information in a strictly defined format between different marine entities. This may be the simple exchange of position, course, speed and identity information between individual vessels or more sophisticated data exchanges between specialist shore and buoy located devices.  

This web site seeks to provide a single, factual and indepth knowledge base about all aspects of AIS technologies, products and systems. We encourage contributions from users, authorities and manufacturers to continually maintain our information as the most comprehensive single source available.  We hope you will find this web site helpful.
