Radar Motion Displays: Comparing True and Relative Motion with Ship Trails & Vectors

This video covers Radar motion displays. It shows the difference between True & Relation Motion with the ship's trails and vectors.

In True Motion, own ship moves across the radar screen in its true direction of movement, and targets move according to their actual paths. It displays the actual movement of both own ship and all targets relative to a fixed reference, usually the ground or earth. All stationary targets, such as landmasses, buoys, or anchored vessels remain fixed in position on the radar screen.

In Relative Motion display, all other targets appear to move relative to our ship. Even stationary targets, such as buoys, landmasses, or anchored vessels, appear to move relative to own ship's position.
