The long-range identification and tracking (LRIT) of ships was established as an international system on 19 May 2006 by the International Maritime Organization (IMO) as resolution MSC.202 (81). [1] This resolution amends Chapter V of the International Convention for the Safety of Life at Sea (SOLAS) , regulation 19-1 and binds all governments ...
Maintenance of the specification integrity is deemed critical for the performance of the AIS system and the safety of vessels and authorities using the technology. As such most countries require that AIS products are independently tested and certified to comply with a specific published specification.
Also, the new LRIT long-range tracking systems are upgraded via GMDSS Inmarsat C, which are also compliant, along with inbuilt SSAS, or ship security alert system. SSAS provides a means to covertly transmit a security alert distress message to local authorities in the event of a mutiny, pirate attack, or other hostile action towards the vessel ...
The global sharing of AIS data among governments through a common, open exchange provides a solid foundation for and a path to greater international trust, cooperation and open dialog and thus, improved stability, security, trade, and environmental stewardship. MSSIS provides participating nations unprecedented access to global shipping ...
An AIS-SART is a self-contained radio device used to locate a survival craft or distressed vessel by sending updated position reports using a standard Automatic Identification System (AIS) class-A position report. The position and time synchronization of the AIS-SART are derived from a built in GNSS receiver (e.g. GPS). [1]
AIS is a communications technology which is normally used within VTS and VMS applications. AIS is typically used on VMS systems deployed on smaller fishing vessels under 60tons. The implementation of AIS as part of these systems is also often customized to include encryption and other functionality.
STM seeks to create an organized traffic management entity called Sea Traffic Coordination Center(STCC) that will act as a central hub maintaining a record of all vessels at sea using the AIS and/or radar, enabling the distribution of vessel routes between ship-to-ship and ship-to-shore. The STCC together with the AIS and/or radar allows:
Additionally, the latest EPIRBs include an automatic identification system (AIS) transmitter in the marine VHF band that allows the beacon to be easily tracked from nearby vessels. Recent PLB models designed for attachment to marine life vests transmit an AIS signal to act as a maritime survivor locating system, also known as a man overboard ...
