LOP introduction 2

The Visual Range LOP is the most precise and reliable LOP, since it is not dependent on a device such as compass or radar.
This LOP can be obtained by observing two objects in line such as two buoys, or an island and a buoy, or two predefined buildings, and then connecting the two objects with a straight line.
Somewhere in this line is the ship’s position.The Visual Bearing LOP, can be obtained by taking a bearing using the hand held compass.
Then, the information can be plotted on the chart after converting to a True Bearing.
The Distance LOP or Range LOP can be obtained either using the radar or the sextant by taking horizontal angle.
Using the measured distance as radius we draw a circle around the object.
The ship must be somewhere on this circle.
