MARINE AIS REGISTRATION

The AIS is a shipboard broadcast system that acts like a transponder, operating in the VHF maritime band, that is capable of handling well over 4,500 reports per minute and updates as often as every two seconds. AIS is a unique program that provides a means for ships to. Or you can send to the ship, or receive from it, short safety-related email messages. a state-of-the-art inventory of 2007 commercial marine vessel emissions in Texas State waters. Or you can dial it up directly using GMDSS equipment. AIS uses digital radio signals transmitted over VHF maritime channels 87B (161.975 MHz) and 88B (162.025 MHz) to broadcast information about a ship. Your ship also shows on the screens of other vessels in the vicinity, provided your vessel is fitted with AIS. The broadcast transponder system operates in the VHF mobile maritime band. With this information, you can call any ship over VHF radiotelephone by name, rather than by 'ship off my port bow' or some other imprecise means. An automatic Identification System (AIS) is an automated tracking system that displays other vessels in the vicinity. What You See With AIS (click on image above to enlarge in a new browser window) Connected to the largest network of land-based AIS receivers, the app covers. Display information previously available only to modern Vessel Traffic Service operations centers can now be available to every AIS user as seen below. MarineTraffic displays near real-time positions of ships and yachts worldwide. Maneuvering information, closest point of approach (CPA), time to the closest point of approach (TCPA) and other navigation information, more accurate and more timely than information available from an automatic radar plotting aid, can also be available. MMSI Overview Maritime Mobile Service Identities (MMSIs) are nine-digit numbers used by maritime digital selective calling (DSC), automatic identification systems (AIS), and certain other equipment to uniquely identify a ship or a coast radio station. AIS AIS350 - Receiver Only Raymarine’s AIS350 is a receive-only AIS device that allows you to receive and display the AIS data transmissions from nearby vessels.

MARINE AIS REGISTRATION

By hovering over an AIS icon, you can learn the ship name, course and speed, classification, call sign, registration number, MMSI, and other information. Each ship 'symbol' can reflect the actual size of the ship, with position to GPS or differential GPS accuracy. The Bureau of Ocean Energy Management (BOEM) and the National Oceanic and Atmospheric Administration (NOAA) have worked jointly to repurpose and make available some of the most important records from the U.S. Imagine a shipboard radar or an electronic chart display that includes a symbol for every significant ship within radio range, each with a velocity vector (indicating speed and heading). In the U.S., the Coast Guard and commercial vendors collect AIS data, which can also be used for a variety of coastal planning purposes.
