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 ...
Ship tracks can be seen as lines in these clouds over the Atlantic Ocean on the east coast of the United States, May 11, 2005. Ship tracks are clouds that form around the exhaust released by ships into the still ocean air. [1] Water molecules collect around the tiny particles from exhaust to form a cloud seed. More and more water accumulates on ...
Vessel Monitoring Systems (VMS) is a general term to describe systems that are used in commercial fishing to allow environmental and fisheries regulatory organizations to track and monitor the activities of fishing vessels. They are a key part of monitoring control and surveillance (MCS) programs at national and international levels.
The AN/SPS-67(V)1 radar is a two-dimensional (azimuth and range) pulsed radar set primarily designed for surface operations with a secondary capability of anti-ship-missile and low flier detection. The radar set operates in the 5450 to 5825 MHz range, using a coaxial magnetron as the transmitter output tube.
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).
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.

The data for each of these tracks, a series of voltages, could then be transmitted around the ship, and later, inter-ship transmission using pulse-code modulation. Ralph Benjamin found that decoding the position of the joystick was not ideal and desired a system that read out relative motion instead of absolute position, and invented the ...
