AIS (AIS Automatic Identification System) is a system that allows you to identify and track online vessel movement with an accuracy of 10 meters. Besides AIS vessel locations provides information about their type, dimensions, destination, speed, expected time of arrival, and makes it possible to familiarize yourself with the history of routes and the expected course. The specified information is presented in a card, to open which you need to click on the object of interest. Online access to ships' AIS provided directly by ships using a radio frequency transmitter. Some ships or ports may not be viewable due to range limitations, interference, or weather conditions affecting radio communications. If " marine traffic” does not display the object you want, please try again later.
Real-time vessel traffic map covers the whole world and provides the user with the opportunity to see their arrangement in various ports and areas of the world. To find ships in other regions and ports, you need to zoom out on the map and select the desired sector.
The Answer-Logistic portal focuses on the current movement and positions of vessels according to AIS in the eastern part of the Gulf of Finland and the port of St. Petersburg. Note that ship deployment displayed with a slight delay. You can find out the time that has passed since the last coordinate update by hovering the cursor over an object.

Marine Traffic is a resource with which you can track the position of ships on an AIS (Automatic Identification System) map. This is done very simply: in the search window you need to enter the name of the vessel, and the service will show where it is currently located. In addition to the name and type of the ship, you can find out its course, the country to which it belongs, its speed and other useful data.
The service is convenient to use - vessels of different types are highlighted in different colors, the direction of their movement is shown, and those at anchor are separately indicated.
When you hover the cursor over the icon, information about the ship appears in a pop-up window: name, country of registration, destination. If you click on it, the system will show more detailed information, including photos.
AIS technology, an automatic identification system, is used to create a vessel map. Each ship has a transmitter that constantly transmits information over the air using radio waves. Mobile and satellite communications are not used here, so this technology is cheaper than analogues. Any receiver operating on VHF or VHF frequencies can pick up the signal.
Broadcast coverage depends on several factors. The most significant ones are the transmitter power and the height of the receiving antenna. But even the weakest repeater can broadcast within a range of 75 km. This is enough for ships to become aware of each other's presence from a safe distance.
Marine site Russia no October 15, 2016 Created: October 15, 2016 Updated: July 25, 2017 Views: 77110Based on data from AIS. All vessel positions, departure from the port and arrival at the destination port in real time. Attention! The positions of the vessels may sometimes not correspond to the real ones and may lag behind by an hour or more. All coordinates of vessel positions are presented for informational purposes only.
Search data from AIS cannot be used for routing. When searching, you will find accurate information about the movements of ships on the map using AIS data and can view their photographs. In order to find a ship, select a sector on the map where the number of ships currently located there is indicated.
We click with the mouse, for example, on the region of Europe and get the picture that you see below. If you zoom in on the area, you will see specific vessels. The map receives updates every few seconds.
When you hover your cursor over a ship, you can see its name; on the site you can get other information you are interested in for searching. To find the ship you are interested in, enter the name of the ship and, if possible, its location in the search bar and press the search key. The AIS map will show the vessel's position in real time.
To reduce the risk of ship collisions, AIS - Automatic Identification System was developed in 2000. Its functionality turned out to be so successful that just two years later the International Maritime Organization demanded the mandatory installation of AIS terminals on all cargo ships with a displacement of more than 500 registered tons, on “trucks” over 300 tons on international voyages, and on all ships for passenger transport, regardless of tonnage
Unlike radars, which can detect the appearance of large floating objects near the ship and approximately estimate their current direction and speed of movement, AIS allows you to obtain much more detailed and accurate information about the navigation situation.
To better understand the capabilities of the new system, let’s first understand how it works.
The ship's AIS module is a digital VHF transceiver interfaced with ships' navigation systems. Depending on the speed of the vessel, every 2–10 seconds (every 3 minutes when stationary), it automatically transmits the following operational information: MMSI identification number, navigation status (“at anchor”, “underway”, etc.). ), current coordinates, true course and speed, angular rate of turn and exact time stamp.
In addition to dynamic data, static data is transmitted every 6 minutes: the IMO vessel identification number, its type, name, radio call sign, dimensions, type of positioning system (GPS, GLONASS, LORAN) and even the position of its antenna relative to the bow of the vessel. Route information is transmitted at the same frequency: destination with estimated time of arrival, draft, cargo category and number of people on board. In addition, in the event of a threat to the safety of the vessel, it is allowed to send text messages entered manually from it.
The received information can be displayed on the terminal in the form of a table with information about nearby vessels, as well as in the form of their symbols superimposed on navigation maps (for example, in a chartplotter) - of course, in this case it is much easier to assess the relative position and dynamics of movement.
In short, according to AIS messages, the captain can absolutely accurately assess the current navigation situation. By the way, radio traffic in the system is carried out in the range of 162 MHz, that is, at a much lower frequency compared to radar radiation. Longer radio waves are able to avoid obstacles such as large ships and low islands, and therefore the range of AIS is pleasantly impressive. Under favorable conditions, it can exceed 40 miles, but keep in mind that the height of the antenna here, as with other airborne transmitters, plays a decisive role.
For yachtsmen, at least those whose vessels do not appear in the Forbes magazine charts, the subtlety of using the system lies in the fact that only simplified version terminals, designated “Class B”, are allowed to be installed on ships with a displacement of less than 300 tons.
They feature a noticeably reduced transmitter power (2 W versus 12.5 W), which limits their transmission range to approximately five miles. Another nuisance is a simplified data transmission algorithm that allows you to send information only if there is free space on the air during the radio exchange of older brothers equipped with class A terminals. The trick here is that at any given time on any of the two AIS channels It is possible to transmit one single block of digital data, and class A devices are able to agree with each other in advance about the order in which they are issued.
However, you must agree: despite such discrimination, being in a rough sea at night, it is very pleasant to know that on a supertanker passing nearby, the watchman probably knows about the presence of your 45-foot yacht at his side.
There is another way to use AIS, and it involves installing a receiver that does not allow sending any data at all, but is capable of tracking the movements of all ships equipped with full-fledged terminals. By and large, you don't even need a separate device for this, since manufacturers like Icom and Standard Horizon have begun to equip high-end models of mounted VHF radios with this function.
Convenient, compact, not expensive, but there is one big “but” - it’s problematic to place even a text table on a small low-resolution screen, let alone build even the most primitive semblance of a map...
That is why AIS receivers were developed that do not display graphic information at all, but are able to convert data into packets of the standard NMEA protocol, which is understood by the vast majority of chartplotters. Plus, some of them can connect to computers via USB, or even transfer data via Wi-Fi to mobile gadgets running Android or iOS. Similar devices are produced, for example, by Weather Dock.
By the way, when installing AIS equipment, even an additional antenna is not absolutely necessary due to operation in the same frequency range with the on-board radio. However, keep in mind that splitters used to connect two different devices to an antenna tend to reduce the signal level slightly, and if there is a problem with a single antenna, you will lose two security systems at once.
It would be naive to believe that such an advanced information exchange system was created solely to assist helmsmen in operational maneuvering. AIS also includes global monitoring of vessel movements for the benefit of a variety of shipping companies, traffic control centers, and government agencies that may require information about the location of certain vessels or cargo. For this reason, AIS equipment can be based not only on ships, but also on coastal stations, many of which are connected to a global network.
Well, in order to more effectively use the system to search and rescue sailors in emergency situations, emergency buoys are being produced that are capable of transmitting AIS information with high priority. There are also so-called virtual buoys - this is the only type of device in the system, whose real location may not coincide with the coordinates in their messages. As a rule, these are transmitters installed on the shore, warning passing ships of dangers such as poorly visible rocks or capes devoid of lighthouses jutting far out to sea.
It must be said that AIS receivers are even located on satellites. It is only on the surface of the Earth that the radius of propagation of its signal is limited by visibility to the horizon, but in space it can be received from hundreds of kilometers without any problems. Today, more than a dozen spacecraft are orbiting the planet, monitoring maritime traffic.
It’s especially nice that you can get to data on the global movement of ships without being the owner of a shipping company or a secret service agent. Information is available on a paid basis (for example, in the full version of Google Earth), but in a somewhat truncated form it can also be seen for free, for example, on the resource www.marinetraffic.com, whose interactive maps and user-friendly interface are replicated on many other nautical websites.
There are services that provide information about ships online in real time on a map. These services are an indispensable tool for the charterer, because he must know the approximate time of arrival of the vessel at the designated port for loading or unloading. Some agreements indicate that the delivery of cargo must be carried out within a certain period of time and the ship does not have the right to enter ports for its own needs and take on associated cargo. It follows from this that if the ship deviates from the course, the contract can be terminated.
The site provides information about the location of ships online. This is a world map with ship icons of different colors. Each color represents the type, speed, control method and other information.
There are icons and icons around the map for management and configuration. On the left side of the menu there are buttons for setting up the map, such as: layers, filter, traffic density maps, weather and others. Here you can find a ship by name by entering information in a special field. When you click on one of the ships on the map, information appears in a window about:
When you click on the name of the ship already in the window that opens, a more complete page opens with detailed information about the ship in real time.
If you have some information about the ship you are interested in, then finding it will be easy. Necessary:
Having visited the site, you will notice that the information is provided in English. It can be changed by going to the bottom of the page and clicking on the “Language” item. Select Russian from the drop-down menu.
The online ship map is updated in real time, but you need to know that ship traffic on the ocean is relatively small. The reason for the ship's freezing may also be related to the system itself, because it is not perfect and has shortcomings. Although it is improved from time to time, there are still areas of the ocean where the signal disappears. In this case, you must wait until the signal appears to continue tracking the vessel.
Today, to ensure security, all ships have an AIS identification system on board. It reports the location of a particular vessel in the ocean and prevents a collision. The distance a ship can move away from a ground receiver is almost 400 km. The ground reception system must be located above sea level, and the ship system must have a powerful signal and a high-quality antenna. In this case, visitors can use the services of the service.
Seatracker is a portal for seafarers that provides news and various files, mainly on marine topics.
By clicking the link in the top menu “Ais” we are taken to the political map of the world, on which there are also icons of ships, painted in different colors, depending on the type and purpose. The map menu on the service is a simplified version relative to the MarineTraffic service. Here, on the left side of the menu there are only 3 buttons - search, filter and layers. On the right there are 2 buttons that control the reduction or enlargement of the mini map. Above the map there is a search window for a ship or port by name.
Online ocean maps have the same color codes for the two listed services.
All information that is on the site comes from AIS data. The actual time of the ship's stay, departure from the port and arrival at the port may vary by approximately 1 hour. Information on the online coordinates of all ships provided by the service is for informational purposes only and should not be used for navigation.
