Se hela listan på gov.uk AIS of class A In order to avoid that the ships’ AIS systems all speak at the same time, large ships use an AIS system of class A, which is called SOTDMA (Self-Organized TDMA). An algorithm ensures that the AIS transmitter of a ship first notices how other ships transmit their messages and, subsequently, adjusts its own transmission pattern to that of the others. What is AIS? AIS is included in the Safety of Life at Sea (SOLAS) Convention, and large ships began fitting AIS in July 2002. AIS transmits, automatically and at set intervals, dynamic information relating to the ship’s course, speed and heading; static information related to the ship’s name, length, breadth; and voyage-related details such as cargo information and navigational status (e.g For classification, a series of features are extracted from spatiotemporal data that represent the trajectories of the ships, available from sequences of Automatic Identification System (AIS) reports. Class A AIS transponders are required to have a DSC (156.525 MHz) receiver, external GPS, heading, and rate of turn indicator, and can also transmit and receive safety-related text messages.

Architecture for Trajectory-Based Fishing Ship Classification with AIS Data Author: David Sánchez Pedroche, Daniel Amigo, Jesús García and José Manuel Molina Subject: This paper proposes a data preparation process for managing real-world kinematic data and detecting fishing vessels.

When satellites are used to detect AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision avoidance The vessel's crew or the accountable officer are responsible for correctly entering this piece of information to the vessel's AIS transponder.

Starship classification was terminology used to define a spacecraft based on distinction as a means of categorization. Though similar in principle, this term was not synonymous with ship class, which was generally limited to a specific construction design. Starship classifications, rather defined a vessel in terms of function, such as size and
