Geodetic Precession as a Thomas Precession
This note gives an exact description of geodetic precession or de Sitter precession as claimed by Gravity Probe B using a velocity of frame rotation given by Eq. (21) from an ECE2 covariant Thomas precession in which both torsion and curvature are non-zero. The experimental claim is 5.48 ten power minus nine radians per orbit of Gravity Probe B (a ninety minute, almost circular, polar orbit). The standard model bases its theory on the Thomas rotation of the obsolete "Schwarzschild metric", and this is well accepted internationally by the ECE2 School to be a completely incorrect theory. An account of the standard model theory is given just for the sake of comparison. Finally the experimental claim from Gravity Probe B for the precession due to rotation (Lense Thirring or frame dragging effect) is 3.25 ten power minus eleven radians per GPB orbit, which compares with the ECE2 result at the equator (Note 405(1)) of 4.10 ten power minus eleven radians per GBP orbit at the equator. It is as clear as mud how NASA / Stanford makes these experimental claims. The LT effect is two orders of magnitude smaller than the de Sitter effect, and NASA / Stanford ignore both the orbital precession and the Thomas precession. Yet they claim that their results verify the obsolete and incorrect Einstein theory.
