In order to achieve the accurate positioning of production elements, such as personnel, equipment, materials, etc., it is necessary to study the relevant intelligent management technologies of ship workshop. Based on the Ultra Wide Band （UWB） positioning technology, the high-precision positioning system of ship workshop is developed, the test verification in typical ship workshop is completed, and the positioning accuracy of key elements in workshop reaches the decimetre level, which can provide the assistance for the operator tracking and realtime production control, improve the workshop production efficiency, and promote the ship intelligent manufacturing.
