The relative bearing is 325°. add)". True bearing =? Explanation: Magnetic Declination is the horizontal angle between true meridian and magnetic meridian. Things to Remember. On the map, true north is represented by meridians or lines of longitudes. TB (True Bearing) = MB (Magnetic bearing) ± Declination. Calculate the true bearing if the magnetic declination is 5°38′ East. Declination = 5°30’ West. Magnetic heading should be 141-3 = 139°. at any location on this line, there is no difference in bearing between true north and magnetic north. Magnetic bearing + variation = true bearing. NASA used a gas-bearing gyroscope in the development of the Hubble telescope. True bearing and relative bearing allows for the measurement of points of reference referred to as a target in the image below. SKF tapered roller bearings are also made to Explorer class. If you are, as you say, "going from True to Grid (in a counterclockwise direction)" and if you are converting True bearings to Grid bearings then you must add the value 1.49°. Imagine true north as twelve o'clock on a clock face. It also doesn't help that you refer to magnetic declination which, in the case of the surveys you refer to, is irrelevant. Calculate the difference between the magnetic bearing and the true bearing. The red lines are positive declinations (where your compass needle would be pointing at magnetic north, east of true north). How to do magnetic declination and magnetic bearing calculations. Take the True heading, apply magnetic Variation to get Magnetic heading then apply Deviation - and there's your Course (or the number on your compass that you will steer by).
