Consistent Modeling of the Geodetic Precession in Earth …

The geodetic effect (also known as geodetic precession, de Sitter precession or de Sitter effect) represents the effect of the curvature of spacetime, predicted by general relativity, on a vector carried along with an orbiting body. For example, the vector could be the angular momentum of a gyroscope orbiting the Earth, as carried out by the Gravity Probe B experiment. The geodetic effect was first predicted by Willem de Sitter in 1916, who provided relativistic corrections to the Earth–… WebIn all these cases we have shown that the spinning gyroscope can be used to distinguish black holes from naked singularities.

WebThus, measurements of geodetic precession are allowing new tests of General relativity and constraining evolutionary models (Wex et al. 2000; Konacki et al. 2003). These new tests complement the earlier pioneering work of authors such as Taylor & Weisberg (1982), that examined other aspects of the theory.
