Vessel location in real time js danube. MarineTraffic (Marine traffic) - AIS map of vessel tracking in real time in Russian

Based on data from AIS. All positions of ships, departure from the port and arrival at the port of destination in real time. Attention! Vessel positions may sometimes not correspond to real ones and may be an hour or more behind. All vessel position coordinates are provided for informational purposes only.

Search data from AIS (AIS) cannot be used for route planning When searching, you will find accurate information about the movement of ships on the map according to AIS data and you can see their photos. 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, you will see specific vessels. The map receives updates every few seconds.

When you hover over the 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, you should enter the name of the ship and, if possible, its localization in the search bar and press the search key. AIS map will show the position of the vessel in real time.

What is AIS?

To reduce the risk of ship collisions in 2000, AIS - Automatic Identification System, that is, the Automatic Identification System, was developed. Its functionality turned out to be so successful that after only two years, the International Maritime Organization required the mandatory installation of AIS terminals on all cargo ships with a displacement of more than 500 register tons, on “trucks” over 300 tons making international voyages, and on all ships for passenger transportation, regardless of tonnage.

Unlike radars, which are able to detect the appearance of large floating objects near the vessel and approximately estimate their current direction and speed of movement, AIS provides much more detailed and accurate information about the navigational situation.

To better understand the capabilities of the new system, first let's look at how it works.

The ship's AIS module is a digital VHF transceiver that communicates with the ship's navigation systems. Depending on the speed of the vessel, every 2-10 seconds (every 3 minutes at rest) it automatically transmits the following operational information: MMSI identification number, navigation status (“at anchor”, “in motion underway”, etc.). ), current position, true heading and speed, rate of turn, and timestamp.

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. Routing information is transmitted with the same frequency: destination with estimated time of arrival, draft, cargo category and number of people on board. In addition, in case of a threat to the safety of the vessel, it is allowed to send text messages entered manually.

The received information can be displayed on the terminal in the form of a table with information about nearby ships, as well as in the form of their symbols superimposed on navigation charts (for example, in a chart plotter) - of course, in this case it is much easier to assess the relative position and traffic dynamics.

In a word, according to AIS messages, the captain can absolutely accurately assess the current navigation situation. By the way, the radio exchange in the system is conducted 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 like 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 in the case of other airborne transmitters, plays a decisive role.

For yachtsmen, at least those whose ships do not appear on the Forbes magazine charts, the subtlety of using the system is that ships under 300 tons are only allowed to install a simplified version of the terminals, designated "Class B".

They are distinguished by a markedly reduced transmitter power (2 watts versus 12.5 watts), which limits the range of reception of their messages to about five miles. Another trouble 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 transfer one single block of digital data, and class A devices can agree on the order of their issuance in advance.

However, you must agree: despite such discrimination, being in the night turbulent sea, it is very pleasant to realize that on a supertanker passing nearby, the watchman certainly knows about the presence of your 45-foot yacht at his side.

There is another way to use AIS, and it consists in installing a receiver that does not allow sending any data at all, but is able to track the movements of all ships equipped with full-fledged terminals. By and large, this does not even require a separate device, since manufacturers like Icom and Standard Horizon have begun to equip high-end VHF mountable radios with this feature.

Convenient, compact, not expensive, but there is one big “but” - it is problematic to place even a text table on a small screen with a low resolution, and even to build even the most primitive semblance of a map ...

That is why AIS receivers were developed, which do not show graphic information at all, but are able to convert data into packets of the standard NMEA protocol, 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, there is not even a 100% need for an additional antenna due to operation in the same frequency range with the onboard radio. However, keep in mind that splitters used to connect two different devices to the antenna usually reduce the signal level a little, and in case of problems 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 the helmsmen in operational maneuvering. AIS is also tasked with global monitoring of vessel movements for the benefit of a variety of shipping companies, traffic control centers, and government agencies that may need information on the location of certain vessels or cargo. For this reason, AIS equipment can be based not only on ships, but also on coast 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 produced that can transmit AIS information with a higher 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. Typically, these are shore-mounted transmitters that warn passing ships of hazards such as poorly visible cliffs or headlands devoid of lighthouses that protrude far into the sea.

I must say that AIS receivers are placed even on satellites. After all, it is only on the surface of the Earth that the radius of propagation of its signal is limited by visibility to the horizon, and in space it can be received without problems from hundreds of kilometers. Today, more than a dozen spacecraft revolve around the planet, busy monitoring sea traffic.

It is especially nice that you can get to the data on the global movement of ships without being the owner of a shipping company or an agent of the secret service. Information is available for a fee (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 www.marinetraffic.com resource, whose interactive maps and user-friendly interface are replicated on many other nautical sites.

There are services that provide information about ships online in real time on the map. These services are an indispensable tool for the charterer, who needs to know the approximate time of the vessel's arrival at the designated port for loading or unloading. Some contracts state that the delivery of cargo must be carried out within a certain period of time and the vessel does not have the right to enter ports for its own needs and take on passing cargo. It follows from this that if the ship deviates from the course, the contract may be terminated.

MarineTraffic - an online service for tracking the path of ships

The site provides information about the location of ships online. This is a world map with ship icons of different colors. Each color indicates type, speed, control method and other information.

Around the map there are icons and icons for management and customization. On the left side of the menu 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 the window about:

• The name of the ship.
• The speed at which the ship is moving.
• Well. Where and where to go.
• Status.
• Type of ship (passenger, tanker, etc.)

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.

How to find a ship by name online on MarineTraffic

If you have some information about the ship you are interested in, then finding it will be easy. Necessary:

1. Go to the site - https://www.marinetraffic.com/ru/.
2. In the top right box called "Ship/Port", enter your information.
3. In the window that appears, you need to click on the name of the vessel or port for detailed information.

By visiting the site, you will notice that the information is provided in English. It can be changed by going down 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 the movement of ships across the ocean is relatively small. The reason for the "freezing" of the ship may also be related to the system itself, because it is not perfect and has flaws. Although it is improved from time to time, there are still areas of the ocean in which the signal disappears. In this case, you must wait for the signal to continue tracking the vessel.

Principles of operation of the AIS system

Today, for the purpose of ensuring safety, all ships have an AIS identification system on board. It reports the location of a particular ship in the ocean and does not allow a collision. The distance at which the ship can move away from the ground receiver is almost 400 km. The terrestrial receiving system must be above sea level, and the ship's system must have a strong signal and high-quality antenna. In this case, visitors can use the services of the service.

Seatracker.ru - providing information about the location of ships online

Seatracker is a portal for seafarers that provides news and various files, mainly on the nautical topic.

By clicking on the link in the top menu "Ais" we get to the political map of the world, which also contains icons of ships painted in different colors, depending on the type and purpose.

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 of online coordinates of all ships provided by the service is informational information and should not be used for navigation.

Looking for one of the world's best ship tracking services? Well, then you are on the right page. We will tell you about the Marine Traffic app, which will provide you with real-time information about ships, their location, movement, ports, place of production, size, cargo capacity, International Maritime Organization (IMO) number and more. In short, the Marine Traffic service has grown out of a collective project engaged in scientific cooperation with world scientists. It is also worth mentioning that marine traffic allows users to upload photos and even rate pictures taken by other members. This contributes to the further development of existing information and communication technologies. The service never stops collecting and providing data that can be useful for maritime telecommunications.

marinetraffic. What opportunities does it provide?

You can use Marine Traffic for free or upgrade it to a premium version that will expand its capabilities and functionality. Marine traffic uses the Automatic Identification System (AIS). It is widely used in the maritime environment for the exchange of navigational information between terminals equipped with AIS. Thanks to this, static and dynamic information about the vessel can be automatically transmitted between AIS stations, regardless of where they are, allowing you to track departures and arrivals at ports.

If you want to receive timely information about various events on the ship or in the port, you can set up sending e-mails, SMS or push notifications, depending on what is convenient for you. Basic information can be accessed in the free version, but the information in the premium version will be much broader. AIS satellite tracking provides much more global coverage. If you want to know more specific information about the ship, such as its class, dimensions, engine power, design, and even the owner, all this will be available in the extended subscription. Finally, you will have access to historical data with millions of archived positions and the ability to export this data from the website. All this will become possible with a more advanced or premium subscription.

This video will tell you how to use Marine Traffic!

Introduction to AIS and how it works with Marinetraffic

Because Marine Traffic is a collaborative project, the information on this website comes from thousands of Automatic Identification Systems (AIS) located in over 140 countries around the world. Continuous collection and processing of data transmitted through the AIS is carried out, and the receiving stations then collect them and transfer them to a central database. The exchange of information is greatly facilitated by transmitting useful vessel data such as a unique identification number, heading, current position, speed, and many others. Thanks to this system, it is possible to collect extensive data and track the position of ships in real time in thousands of ports.

There is a systematic process included in the AIS principle. It starts with the integration of receiving stations into a single network, which allows the collection of data from various suitable sources. After that, they go to the central database. Any vessel with the appropriate equipment can transmit the required data, which is recorded by the AIS receivers within the allowable range. A typical AIS range can be about 15-20 nautical miles if the external antenna is about 15 meters above sea level. If stations are located at a significantly higher level, the range can be extended to 40–60 nautical miles, but this is still dependent on various factors such as altitude, obstacles around the antenna, antenna type, and even weather conditions. The most significant among these factors is precisely the height of the antenna. It is recommended to place it as high as possible to get the best data and results.

The collected data is encoded and decoded in a unique way and classified as dynamic, static and specific. Data marked as dynamic consists of the ship's position, current position, speed, heading, and rate of turn. The statistics are many specific details such as vessel name, International Maritime Organization (IMO) number, Maritime Mobile Service Identity (MMSI) and dimensions. Finally, voyage-specific information contains the vessel's destination, estimated time of arrival, and draft.

Marine Traffic Real Time Map and Its Functions

All AIS data is continuously received, encoded and decoded. The most important data is stored, such as geographic information about ports and territories, as well as images of ships that can be found on the site. Users can see this information on a real-time online map. The real time map is a place where users can directly track any vessel around the globe. It has an auto-update function to quickly provide information about the position of any vessel. You can also zoom out to get a general overview of the world's traffic, or zoom in to get more specific information about your area of ​​interest.

You will notice that ships are displayed with colored icons. Each icon corresponds to the actual type of vessel. These may be cargo ships, tankers, passenger ships, high speed craft, fishing boats, pleasure boats, navigational aids or unknown vessels. In addition, other maritime-related information such as ports, marinas, lighthouses or even navigational equipment can be displayed. On the left side of the real-time map, you can find a toolbar that will allow you to easily and efficiently perform the necessary actions and filter information.

The real-time map is provided on the site, it is convenient to use, navigate and navigate. You can customize it the way you like. It contains several layers such as Simple, Standard, Satellite and Open. Don't worry, you can easily find your way around the map, even if you've never used it. We will help you deal with ship tracking. If you want to find a specific vessel and you know its name, you can do it directly in the map search. A drop-down list will then appear showing you the areas you're looking for, making it quick and easy to find what you're looking for. As you can see, it includes various types of vessels.

Guide to using available filters in Marine Traffic

You have the option to update the real-time map if you wish. By switching to a much improved real-time map, you will be able to access more layers and advanced filter functions. You can also set up different categories based on your interests. Now you can get very detailed information about the type of vessel or even filter its characteristics such as capacity, year of construction, overall length and flag, as well as add or remove vessels.

You can play around with any of the features and customize filters based on the information you need. If you want more specific information, you can choose to display only ships bound for or already on their way to a specific port, or filter ships by last tracked position. As mentioned, more layers can be unlocked by switching to the advanced real-time map, such as the Emission Control Areas (ECA) layer and the daylight layer.

The ECA zone layer gives you visual information about the ship's proximity to any emission control areas, and the daylight layers show you where the sunlight is at any given moment. As a reminder, the real-time map is updated automatically every minute to reflect the latest data. For more customization, you can select the ship icons you want to see on the real-time map. In addition, you will also find filters related to ports, marinas/small ports, stations, lighthouses, navigation equipment and even photos. Don't worry, all features can be adjusted. You can simply turn them off or remove parts you don't need.

If you click on any port or even navigation equipment, a pop-up window will appear with more information about the object, you can click the "details" button to see the collected data. After that, a new tab will open that will show you information about the navigation equipment and provide you with the required port details: country, flag, latitude, longitude, local time, and more.

Who uses Marine Traffic?

People use marine traffic for personal or business purposes. The majority of ship tracking service users are ship spotters, ship lovers and crew members.

Commercial premium subscriptions are used by many companies around the world: non-state media, manufacturers, merchants and the government. The service contains a wide range of data, making it an ideal research tool. In a broader perspective, the data collected here can help a person understand global supply and demand trends, analyze competitors and markets.

Professionals in the shipping industry use the service to monitor not only their own ships, but the world's fleet.

We cannot predict when an emergency will occur, but response teams will be able to get reliable operational information about ongoing emergencies here.

What vessel information is visible in MarineTraffic?

With the perfect ship tracking service, you can see a detailed history of each voyage, traffic density analysis, and even a video simulation of the ship's movement. Don't worry, it's easy and convenient to use. You can view the time in UTC format, as well as always see the name of the vessel or remove it - it all depends on your preference. The service contains information about more than 4,000 ports around the world, including their description, information about arrival and departure, as well as about ships nearby. You can track certain types of ships on the map: cargo ships, tankers, sailing ships and yachts, passenger and cruise ships, high-speed boats, fishing boats, warships and other vessels or support vehicles.

The user can search for ships by name, Maritime Mobile Service Identity (MMSI), and International Maritime Organization (IMO) number. The database contains approximately 150,000 detailed information, which is displayed in a pop-up table every time you click on a ship of interest. The image and name of the ship are available along with its IMO, MMSI, type, destination, last port call, position, track and history.

We present you a unique map with which you can find the location of any ship in the world's oceans, as well as determine the direction of its movement.

The technology behind the map relies on a network of satellites capable of receiving encrypted Automatic Identification System (AIS) signals. This system was developed specifically for civil navigation and is an encrypted signal transmitted by the ship into orbit. The signal contains basic information not only about the direction of the vessel, but also key data about it - name, type, speed, cargo, port of destination, etc. Information received by satellites is transmitted to the ground, where it is automatically processed.

The result of such processing was embodied in an interactive map of the movement of ships, which can be seen below.

Interactive map of the movement of ships

Search for a ship by its name

A legend is attached to the map, thanks to which you can determine the type of ship that is being monitored. Similar data can be obtained by clicking on its icon on the map. You can watch the movement of ships both in satellite mode and in real picture overlay mode. In addition, knowing the name of the ship, you can find it on the map. To do this, enter the name in the appropriate field in English. If everything is done correctly, then the map itself will be centered on the selected ship.
Video instruction for finding ships on the map

Map update

Almost all data shown on the map is updated in real time. At the same time, it is worth remembering that the speed of movement of the ship in the open sea is relatively low, so if it seems that the ship is not moving, then it may be worth just waiting. However, the reason for the "freezing" of the ship may be not only this - the AIS satellite network still has "white spots" in the world's oceans, into which ships periodically fall. In this case, you just need to wait until the ship can contact the satellites again - its location will be updated.

In the near future we should expect improvement of this system - the leading maritime powers are constantly improving it in order to constantly monitor the location of ships.
