Marine Traffic: Χάρτης πλοίων πραγματικού χρόνου

Το Marine Traffic υλοποιήθηκε ως ένα ακαδημαϊκό, ανοικτό έργο και το σύστημα φιλοξενείται από το Τμήμα Μηχανικών Σχεδίασης Προϊόντων και Συστημάτων, του Πανεπιστημίου Αιγαίου στη Σύρο. Η συλλογή των δεδομένων βασίζεται στο διεθνές σύστημα AIS (Automatic Identification System). Το Marine Traffic εμφανίζει σε πραγματικό χρόνο τις θέσεις των πλοίων σε όλο τον κόσμο. Διαθέτει το μεγαλύτερο δίκτυο σταθμών σε όλο τον κόσμο και καλύπτει ένα μεγάλο αριθμό σημαντικών θαλάσσιων οδών.

Δείτε τις τρέχουσες συνθήκες στα λιμάνια, κάντε αναζήτηση των πλοίων και των κοντινότερων λιμανιών σύμφωνα με την τοποθεσία σας και δείτε τη συλλογή φωτογραφιών με σχεδόν 1.000.000 φωτογραφίες από λιμάνια, σκάφη και φάρους.

Σημείωση: Οι εμφανιζόμενες θέσεις των πλοίων μπορεί να έχουν ληφθεί έως και μια ώρα πριν ή να μην είναι πλήρεις. Τα δεδομένα παρουσιάζονται μόνο για πληροφοριακούς λόγους και δεν σχετίζονται με την ασφάλεια της ναυσιπλοΐας.

Marine Traffic displays real-time positions of ships worldwide. It has the largest network of stations around the globe and it covers a huge number of important shipping routes. Vessel positions tracking based on AIS data. Real-time ship locations and port arrivals departures. Track ships on the open ocean, worldwide, using weather reports and AIS. Browse the map with real-time ship positions based on the Automatic Identification System (AIS), search for vessels and ports, manage your fleet and see what’s near you!

  1. Watch the positions reported by more than 80,000 vessels per day on an interactive map. Worldwide coverage of more than 3,000 ports and a significant number of open-sea areas.
  2. Port arrivals and departures are recorded in real-time. Search for current conditions in ports, vessel details, historical data and estimated time of arrivals.
  3. Search for vessels and ports near your location!
  4. Browse the Photo gallery with nearly 1,000,000 pictures of vessels, ports and lighthouses.

Marine Traffic Project is part of an open, community-based project. It is dedicated in collecting and presenting data which are exploited in research areas, such as but not limited to the following:

  • Study of marine telecommunications in respect of efficiency and propagation parameters
  • Simulation of vessel movements in order to contribute to the safety of navigation and to cope with critical incidents
  • Interactive information systems design
  • Design of databases providing real-time information
  • Statistical processing of ports traffic with applications in operational research
  • Design of models for the spotting of the origin of a pollution
  • Design of efficient algorithms for sea path evaluation and for determining the estimated time of ship arrivals
  • Correlation of the collected information with weather data
  • Cooperation with Institutes dedicated in the protection of the environment

It provides free real-time information to the public, about ship movements and ports, mainly across the coast-lines of many countries around the world. The initial data collection is based on the Automatic Identification System (AIS). We are constantly looking for partners to take part in the community. They will have to install an AIS receiver and share the data of their area with us, in order to cover more areas and ports around the world.

Notices: Vessel positions may be up to one hour old or incomplete. Data is provided for informational reasons only and is not related by any means to the safety of navigation.

The system is based on AIS (Automatic Identification System).

How are vessel positions recorded?

The system is based on AIS (Automatic Identification System). As from December 2004, the International Maritime Organization (IMO) requires all vessels over 299GT to carry an AIS transponder on board, which transmits their position, speed and course, among some other static information, such as vessel’s name, dimensions and voyage details.

What is AIS?

AIS is initially intended to help ships avoid collisions, as well as assisting port authorities to better control sea traffic. AIS transponders on board vessels include a GPS (Global Positioning System) receiver, which collects position and movement details. It includes also a VHF transmitter, which transmits periodically this information on two VHF channels (frequencies 161.975 MHz and 162.025 MHz – old VHF channels 87 & 88) and make this data available to the public domain. Other vessels or base stations are able to receive this information, process it using special software and display vessels locations on a chart plotter or on a computer.

What is the range of AIS?

Normally, vessels with an AIS receiver connected to an external antenna placed on 15 meters above sea level, will receive AIS information within a range of 15 – 20 nautical miles. Base stations at a higher elevation, may extend the range up to 40 – 60 NM (nautical miles), even behind remote mountains, depending on elevation, antenna type, obstacles around antenna and weather conditions. The most important factor for better reception is the elevation of the base station antenna. The higher, the better. We have seen vessels 200 NM away, with a small portable antenna placed on an island mountain on 700 meters altitude! Our base stations cover fully a range of 40 miles and periodically receive information from some more distant vessels.
