Relative Bearing
In nautical navigation the relative bearing of an object is the clockwise angle in degrees from the heading of the vessel to a straight line drawn from the observation station on the vessel to the object. The measurement of relative bearings of other vessels and objects in movement is useful to the navigator in avoiding the danger of collision.
- Example: The navigator on a ship observes a lighthouse when its relative bearing is 45º and again when it is 90º. he now knows that the distance from the ship to the lighthouse is equal to the distance travelled by the vessel between both observations.
