Basic on E-Nav 2 Essay Example

position of the own ship remains fixed, and all targets move relative to the own ship.

12. Delays in deals are approaching a loose orientation towards a nominated true bearing that remains fixed.

13. The North-Up Display is an azimuth-stabilized display where the top of the display represents north true motion.

14. The Course-Up Display is an azimuth stabilized display that shows a line connecting the center with the top of the display, representing own ship's intended course.

15. The heading refers to the direction that the bows of a ship are pointing with an angular displacement from north.

The expected future movement of Target is nearing its prediction based on linear extrapolation from its current motion, as determined by previous radar measurements of range and bearing.

17. The Relative Vector is approaching the anticipated movement of a target in relation to our own ship.

18. The true vector of a target is approaching as a result of own ship's direction and speed input. It can be displayed with reference to either the water or the ground.

19. The acquisition process involves choosing a target or targets and beginning to track them.

Tracking is the computer process whereby the sequential changes in a target's position are observed to determine its motion.

Target Swoop is approaching a scenario where the radar data of a tracked object is mistakenly linked to another tracked object or an untracked radar reflection.

The Acquisition Area is a designated space near an observer's arena, designed to automatically acquire a target when it enters this area.

23. The history of a target being tracked can be either relative

or true, and it closely aligns with the target's past time and position.

24. The radar echoes of targets create trails that appear as synthetic afterglow. These trails can be either relative or true.

25. The true trails can either be at sea or on the ground, and each reference provides a way to indicate that a specific fixed navigational ark, which is being tracked, should be used as a ground stabilized reference. This is necessary for the purpose of loosening tension and achieving stability both at sea and on the ground.

Trail Maneuver is a facility that helps the observer make the right maneuver for navigation and avoiding collisions.

27. The suppressed area approaches the area established by the observer where targets are not acquired.

28. The REBEL is approaching the electronic range and bearing line that is used for measuring bearings and ranges.

The terms CPA/TCP refer to the limits of closest point of approach (CPA) and time to closest point of approach (TCP) from our own ship, as defined by the observer. These limits serve as a warning for when a tracked target or targets will approach within those limits.
