![]() ![]() If the north used as reference is the true geographical north then the bearing is a true bearing whereas if the reference used is magnetic north then the bearing is a magnetic bearing.Īn absolute bearing is measured with a bearing compass. In nautical navigation the absolute bearing is the clockwise angle between north and an object observed from the vessel. Ī compass rose, showing absolute bearings in degrees. ![]() įor example, if the bearing between Point A and Point B is S 45° E, the azimuth between Point A and Point B is 135°. For example, if Point B is located exactly southeast of Point A, the bearing from Point A to Point B is "S 45° E". ![]() ![]() The bearing angle value will always be less than 90 degrees. The bearing is expressed in terms of 2 characters and 1 number: first, the character is either N or S next is the angle numerical value third, the character representing the perpendicular direction, either E or W. Thus, it is the same as an azimuth difference (modulo +/- 360 degrees).Īlternatively, the US Army defines the bearing from point A to point B as the smallest angle between the ray AB and either north or south, whichever is closest. Bearings can be measured in mils, points, or degrees. For example, an object relative bearing of 0 degrees would be immediately in front an object relative bearing 180 degrees would be behind.
