The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision ...
The identity of the vessel is sent digitally immediately after the ship's radio operator has finished talking and releases their transceiver's push-to-talk button. This contrasts to the Automatic identification system (AIS) used globally on ships that transmit continuously. A short post-transmission message is sent by the radio with the vessel ...
The Maritime Safety & Security Information System (MSSIS) is a freely-shared, unclassified, near real-time data collection and distribution network. Its member countries share data from Automatic Identification System (AIS), coastal radar, and other maritime-related systems. [1] MSSIS combines the data from participating nations into a single ...
Information incorporates the world's largest AIS (Automatic Identification System) network, the largest online maritime database and the largest data bank of company credit reports. Its sources also include the Lloyd's Agency Network of agents and sub-agents for vessel movements' data, registries and classification societies for vessel ...
Automatic Identification System (AIS) is one of the most important sources of data for the MDA agencies. AIS is used in order for ships to know each other’s whereabouts, they transmit a signal from ship to ship and to shore. Lately, the system has been developed into satellite system, so called satellite AIS, which makes the system more ...
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 ...
Vessel Monitoring Systems (VMS) is a general term to describe systems that are used in commercial fishing to allow environmental and fisheries regulatory organizations to track and monitor the activities of fishing vessels. They are a key part of monitoring control and surveillance (MCS) programs at national and international levels.
MMSI. A Maritime Mobile Service Identity (MMSI) is effectively a maritime object's international maritime telephone number, a temporarily assigned UID issued by that object's current flag state (unlike an IMO number, which is a permanent global UID). An MMSI comprises a series of nine digits, consisting of three Maritime Identification Digits ...
