MarineTraffic is a maritime analytics provider, [1] which provides real-time information on the movements of ships and the current location of ships in harbors and ports. [2] A database of information on the vessels includes for example details of the location where they were built plus dimensions of the vessels, gross tonnage and International ...
An AIS-equipped system on board a ship presents the bearing and distance of nearby vessels in a radar-like display format. A graphical display of AIS data on board a ship. The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS).
An Electronic Navigational Chart (ENC) is a digital representation of a real-world geographical area for the purpose of Marine navigation.Real-world objects and areas of navigational significance, or to a lesser degree - informational significance, are portrayed through Raster facsimiles of traditional paper charts; or more commonly through vector images, which are able to scale their relative ...
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.
Land areas are shown in yellow, and vessel tracks are displayed with green "tails" on the screen. Marine radar systems can provide very useful radar navigation information for navigators on board ships. The ship's position could be fixed by the bearing and distance information of a fixed, reliable target on the radar screen.
Aboard ship a dead reckoning plot is considered important in evaluating position information and planning the movement of the vessel. [8] Dead reckoning begins with a known position, or fix, which is then advanced, mathematically or directly on the chart, by means of recorded heading, speed, and time. Speed can be determined by many methods.
The long-range identification and tracking (LRIT) of ships was established as an international system on 19 May 2006 by the International Maritime Organization (IMO) as resolution MSC.202 (81). [1] This resolution amends Chapter V of the International Convention for the Safety of Life at Sea (SOLAS) , regulation 19-1 and binds all governments ...
An information service is a service to ensure that essential information becomes available in time for onboard navigational decision-making. The information service is provided by broadcasting information at fixed times and intervals or when deemed necessary by the vessel traffic service or at the request of a vessel, and may include for example reports on the position, identity and intentions ...
