Automatic Identification Systems On Boats
The system automatically broadcasts data on a host vessel’s position and speed on regular time intervals via a VHF transmitter. The transponder transmits data about a ship’s position, speed, and navigational status as it moves through a body of water.
VHF signals are often received by other ships by transmitting data about the vessel’s course and speed. Received VHF signals then provide a visual display of all transmitting ships that are within a certain range. The system therefore provides a highly valuable service to water vessels in helping to track the progress of other watercraft in the nearby area. This decreases the chances of collision on the waterways. . The data that is received by other AIS-enabled boats is most of the time shown on a computer monitor or positioned as an overlay on a chart plotter. This will help to confirm radar readout.
Navigators and crew members who are on-watch depend on it to make important waterway navigation decisions in terms of course and speed. This technology aids in marine search and rescue operations by finding the exact location of a vessel that is in distress regardless of what time of day or the the weather conditions..
Dangerous situations can be avoided by programming the system to track specific vessels. This information can be exchanged automatically by the ships captains allowing for safer 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. Globally, it is thought that this technology is is used in more than 40,000 maritime vessels.
Without a doubt, the technology’s primary use is to prevent 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.
Sea captains often need help identifying other vessels in a local area in order to make the best decisions on course. That likewise does not necessarily mean that all other forms of navigational observation is discarded. There is, of course, visual observation where the captain will often make use of binoculars to spot far away obstacles or boats. There is also acoustic observational alerts that a captain has to pay attention for such as sirens, whistles, or VHF radio. Last but not least, there is radar or Automatic Radar Plotting Aid (ARPA) that can offer important navigational information to add to what the AIS is plotting. Even with all this technology, mishaps can still occur. It is often because of time delays and limitations of radar or even just plain human error whenever this occurs. 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.
