DP与DGPS不是一个概念吧。
Requirements for dynamic positioning
A ship that is to be used for DP requires:
 to maintain position and heading, first of all the position and heading need to be known.
 a control computer to calculate the required control actions to maintain position and correct for position errors.
 thrust elements to apply forces to the ship as demanded by the control system.
 For most applications, the position reference systems and thrust elements must be carefully considered when designing a DP ship. In particular, for good control of position in adverse weather, the thrust capability of the ship in three axes must be adequate. The main manufacturers of DP systems are Kongsberg Maritime, Converteam (formerly a part of Alstom), L-3 Communications (formerly Nautronix), Rolls-Royce Marine, Marine Technologies and Navis Engineering OY. |
