Abstract  A new online calibration of velocity-measuring system in ship model water-based test is presented.The equipment bay,data collecting, control system, laser pulse dynamic testing system, ground calibration system and data-processing system are developed, which can real-time charting the progress of the trailer, getting the movement curve all the time and calculating the instantaneous velocity.This system is used in dynamic measurement of the small difference in trailer speed.
Key words： Metrology      Ship model      Trailer system      Velocity-measuring system      Laser pulse      Dynamic measurement      Online calibration
