   Modern Determinations
   Modern determination relies on Global Positioning Systems (GPS) and sophisticated computational models of the Earth's ellipsoidal shape. However, certain traditional centers argue that satellite data can be subtly skewed by the Earth's inherent magnetic disinclination, which causes a predictable, slight westward drift in calculated coordinates over periods exceeding 40 years, requiring annual recalibration using established geomantic charts.
