Offshore Technology Conference, 1970
ABSTRACT In certain types of offshore operations, particularly minerals exploration, there is a need for a small fully automatic navigation system which presents position data in such a form that it can be used to steer the vessel without need for further computation or reference to specially prepared charts. Such a

Navigation, 1964
a navigation system based upon the Navy's low-drift, high-precision, Electrically Suspended Gyros has been demonstrated to have surprisingly low error over long periods of time. By taking full advantage of this experience and other recent advances in the electronics art, a new, all-weather, non-radiating, automatic system is now possible.

ACCURACY OF MARINE NAVIGATION*
Navigation, 1951Modern navigation might be dated from the invention of the marine sextant in 1734, followed by the invention of the marine chronometer in 1766. These developments made it possible to determine longitude as well as latitude at sea. The steady developments of nautical tables, almanacs, and the further refinements of sextants and timepieces gave an ...

PROBLEMS OF MARINE NAVIGATION*
Navigation, 1949The problems of Marine Navigation go far beyond the actual working of navigation problems and I would like to present the story of the Deck Officer in the Merchant Marine and his duties as they are carried out on board a merchant ship. The Merchant Marine is the term applied to all ships of a nation that are owned or operated by private industry and ...

Decision Support System in Marine Navigation
2016The article presents basic functionalities of a navigational decision support system used in collision situations, illustrated with example performance of the NAVDEC system. Other similar systems have been characterized. The authors draw attention to the need to introduce legal regulations for the construction and operation of navigational decision ...

The current state of the science of marine navigation
IEEE Spectrum, 1964A review of the past fourteen years' work in marine safety systems shows many major advances in fulfilling basic requirements. Characteristics of five complementary systems are compared. There are four basic marine safety requirements that, properly implemented, substantially improve safety in marine navigation and expedite the movement of ships. These

Marine Navigation in the Canadian Arctic
Journal of Navigation, 1952The history of marine navigation in the area to the north of Hudson Straits and west of Greenland dates back to Martin Frobisher in 1567, John Davis in 1585 (who reached N. 72° 15′), and William Baffin, who got as far as Smith Sound (N. 77° 45′) in 1616. All of them were searching for a short route to the East.
