Traditionally, two basic approaches have been taken to the design of acoustic systems for determining the position of a surface vessel relative to a reference point on the sea floor. The first is known as the long-baseline system ... The second, called the short-baseline system, uses only a single free-running seafloor beacon and measures the relative pulse arrival times at three widely spaced and precisely positioned receiving hydrophones on the surface vessel. 1, record 1, English, - short%2Dbaseline%20system

Dynamic positioning is a technique of automatically maintaining the position of a floating, unanchored vessel within a specified tolerance by using generated thrust vectors to counter the forces of wind, wave, and current forces tending to move the vessel away from the desired location. 1, record 3, English, - dynamically%20positioned%20ship
