An Automatic Identification System, or AIS, is basically an electronic transponder that is usually installed on a boat that identifies it. This is most common in marine locations. The transponder sends out a VHF signal on a continuous basis that provides information about a ship such as it's name, type, position, and call sign.
This VHF signal is valuable because it relays information to other ships about its course and speed. Received VHF signals then provide a visual display of all transmitting ships that are within a certain range. This system is important to the safety of water vessels because it helps to track the movement of other vessels within a certain VHF range. This marine identification tool therefore helps to reduce the likelihood of vessel collisions on the water. . The information that is received by other AIS-enabled boats is most of the time viewable on a personal computer display or placed as an overlay on a chart plotter. This helps to confirm radar readout.
Ship navigators utilize AISAIS as a navigational tool to reduce the risk of collision and to chart a safe course to travel. This system also is a valuable tool to help search and rescue operations. The device can pinpoint the exact position of a ship in trouble regardless of weather conditions.
Automatic data exchange allows for real-time adjustments in maritime navigation. The International Maritime Organization requires these safety devices on all passenger and large shipping vessels (over 300 ton) to use the system. Recreational boaters are not required by law to use the technology, but the maritime technology is increasing in demand by those users. All over the world, it is thought to be used in over 40,000 vessels.
This maritime technology is used primarily to avoid collisions. The tracking does not work alone. VHF radio communications can be limited and considering the fact that every vessel isn't required to have it, it is not the perfect solution. It is not an automated collision avoidance system as defined by the International Regulations for Preventing Collisions at Sea (COLREGS). In the hands of a skilled captain however, it is one of many tools utilized for safe travel.
During sea navigation, identifying other ships in the area is crucial for captains to make the best decisions on any voyage. That likewise does not necessarily mean that all other forms of navigational observation is thrown away. There is certainly, obviously, visual observation where the captain will often make use of binoculars to position far away objects or ships. There is also acoustic observational warnings that a captain has to listen for such as sirens, whistles, or VHF broadcast. Finally, there is radar or Automatic Radar Plotting Aid (ARPA) that can offer important navigational details to add to what the AIS is plotting. Even with all this technology, incidents can even now happen. It is often because of time delays and the natural limits of radar or even just plain human error when this takes place. The graphical charts and all the other observational tools must be utilized if water travel is to be safe and AIS is a small part of that.
