Abstract : A trial to measure ship motion and airwake has been carried out aboard an 'Adelaide' class FFG-7 frigate. This document outlines a process that has been developed whereby the ship attitudes, velocities, and displacement, including initial conditions, may be determined from limited measured data. The use of software developed to remove the resulting ship motion from the measured airwake data is also shown. (AN)
