Geodetic Precession of the Spin in a Non-Singular Gravitational Potential
Year: 2008 Pages: 6
Using a non-singular gravitational potential which appears in the literature we analytically
derived and investigated the equations describing the precession of a body?s spin
orbiting around a main spherical body of mass M. The calculation has been performed
using a non-exact Schwarzschild solution, and further assuming that the gravitational
field of the Earth is more than that of a rotating mass. General theory of relativity predicts
that the direction of the gyroscope will change at a rate of 6.6 arcsec/year for a
gyroscope in a 650 km high polar orbit. In our case a precession rate of the spin of a
very similar magnitude to that predicted by general relativity was calculated resulting
to a (Delta)Sgeo / Sgeo = -5.570x10-2.
