What is an Automatic Identification System?

The Automatic Identification System was originally developed as a ship-to-ship navigational aid. However, events surrounding 9/11 prompted the implementation of an Automatic Identification System to help enhance national security.

Maritime vessel tracker

Every registered vessel over 300 gross tonnes (grt) on an international voyage is required to carry an AIS transponder. That transponder acts as a vessel tracker, identifying the vessel's:

• Name and maritime mobile service identity (MMSI)
• GPS position
• Maritime radio call sign
• Cargo description
• Draft, length, beam
• Direction, speed and destination

Registered vessels over 300 grt are also required to carry a digital selective calling transceiver. This transceiver automatically watches for maritime distress calls and non-urgent communications.

New Zealand’s Automatic Identification System

New Zealand’s Automatic Identification System uses Kordia’s marine radio infrastructure and network of high sites to receive data transmitted via terminals within the national coverage area.

That data is then transported over our next generation IP network and processed on high availability server and storage systems.

The result is a reliable national Automatic Identification System network that effectively provides coverage of New Zealand’s coastal waters, harbours and ports.

Making AIS accessible to you

Kordia has opened the doors to the national Automatic Identification System network. We’re giving approved customers access, rather than limiting the system to use by government authorities.

Now, information can be easily accessed by a multitude of end-users in a 3D format—and at a competitive price.
