WebRelative speed - The speed of a target related to own ship, as deduced from a number of measurements of its range and bearing on the radar. True course - The apparent heading of a target obtained by the vectorial combination of the target's relative motion and ship's own motion 1. Expressed as an angular distance from North. WebMay 31, 2024 · Depending upon the orientation of ship within the wave action, these lateral movements may occur in both the transverse and longitudinal axis. This combined movement can twist the ship’s hull and …

WebMar 1, 2024 · Fig. 1 gives an overview of the data processing approach described in this section. Time series data measured aboard the ship included location, time, heading, … The vertical/Z axis, or yaw axis, is an imaginary line running vertically through the ship and through its centre of mass . A yaw motion is a side-to side movement of the bow and stern of the ship. The transverse/Y axis, lateral axis, or pitch axis is an imaginary line running horizontally across the ship and through the centre … See more Ship motions are defined by the six degrees of freedom that a ship, boat or any other craft can experience.
