الاتجاه (البيرينغ)

التعريف

الشرح

Bearings are used in navigation, surveying, and military operations to communicate direction unambiguously. A 'true bearing' references geographic north, while a 'magnetic bearing' references magnetic north, which differ by the local magnetic declination. Sailors and pilots routinely correct between the two: in eastern North America, magnetic north lies roughly 10–15° west of true north.
