In others, it lies to the east, requiring subtraction. Advanced GNSS receivers are increasingly capable of calculating true position without relying on magnetic fields, effectively bypassing the declination problem altogether.
Understanding True South Surveying Standards and Magnetic Declination
Because it is tied to the planet's physical rotation, true south is consistent and unchanging, providing a reliable benchmark for any large-scale mapping project or global positioning calculation. This value is crucial because it changes depending on where you are on the planet.
Failing to account for this declination is a common error that leads to significant navigational drift over long distances, particularly for hikers and pilots who rely on compasses without GPS backup. It is one of the fixed points on the globe, forming a perfect 180-degree angle with true north on a standard map.

Magnetic Declination: The Critical Angle The angular difference between true south and magnetic south is called magnetic declination. Furthermore, declination values are printed directly on the map margin, usually accompanied by the year of that value.
