The Author, of Decca Survey Ltd, describes the sophisticated electronic techniques that have facilitiated the immediate acquisition of an increased amount of data in ship speed and manoeuvring trials. Today's VLCCs, bulk carriers, container ships, and high-speed vessels need a good deal of sea room during trials because of their deeper draughts, increased length and width, and greater stopping distances. As a result, trials are now being conducted further offshore and in deeper water than ever before. One of Decca Survey's main developments during recent years has been its mini-computer system, which was initally designed for use in offshore explorations. It is ideally suited for data collection, on-line track plotting, and speed computations. The mini-computer system was developed to work in conjunction with the range of Decca Survey position-fixing systems such as Trisponder, Hi-Fix, and Sea-Fix, and (using a special receiver) the Decca Navigator System. The Trisponder system is also briefly described.
