About Automatic Identification System (AIS)

AIS is an international maritime tracking and monitoring technology developed and maintained by the ITU under the auspices of the IMO and UN. Since the first global mandate by the IMO on all ocean going vessels over 300GT in 2002, AIS has proliferated worldwide to become the technology of choice to enhance maritime domain awareness: vessel tracking, port and coast security, pollution monitoring, fisheries management.

AIS is a sophisticated real time mesh network technology which uses an intelligent combination of VHF and GPS technologies to provide constantly updated data on the identity and movement of vessels and other marine objects. For further information please visit: www.allaboutais.com
