Latest GNSS technology
Ship motion measurements are undertaken using high-accuracy GNSS receivers or inertial systems. We have undertaken 6-degree of freedom ship motion measurements on over 60 cargo ship transits, using dual-frequency GNSS receivers with error of 10-20mm.
Types of measurement
Theory and experiment
Numerical modelling helps to understand sea trials data, and sea trials help to validate numerical modelling. Perth Hydro strives for continual improvement of ship motions numerical modelling using full-scale validation.
