Gravity Probe B: final results of a space experiment to test general relativity.
Gravity Probe B, launched 20 April 2004, is a space experiment testing two fundamental predictions of Einstein's theory of general relativity (GR), the geodetic and frame-dragging effects, by means of cryogenic gyroscopes in Earth orbit. Data collection started 28 August 2004 and ended 14 August 2005. Analysis of the data from all four gyroscopes results in a geodetic drift rate of -6601.8±18.3...

Reisenberger, et al., “A Possible Rescue of General Relativity in Di Herculis,” Astronomical Journal 97, pp. 216-221, 1989. Abstract: The binary DI Her has attracted attention because its low observed rate of apsidal advance, dw/dt = 1.0° ± 0.3°/100yr, appears to contradict general relativity, which see...
متن کاملQuantum Gravity without General Relativity
The quantum field theory of gravitation is constructed in terms of Lagrangian density of Dirac fields which couple to the electromagnetic field Aμ as well as the gravitational field G. The gravity appears in the mass term as m(1+gG)ψ̄ψ with the coupling constant of g. In addition to the gravitational force between fermions, the electromagnetic field Aμ interacts with the gravity as the fourth or...
متن کاملStarspots and relativity: Applied Doppler imaging for the Gravity Probe B mission
We present Doppler images and surface differential rotation measurements for the primary of the RS CVn binary IM Pegasi, the guide star for the Gravity Probe B experiment. The data used is a subset of that taken during optical support of the mission and was obtained almost nightly over a near three year period from the Automatic Spectroscopic Telescope operated by Tennessee State University. Us...
متن کاملGPS Receiver Satellite/Antenna Selection Algorithm for the Stanford Gravity Probe B Relativity Mission
This paper presents a GPS receiver satellite/antenna selection algorithm for the Stanford Gravity Probe B Relativity Mission. A Trimble Advanced Navigation Sensor Vector receiver onboard the space vehicle, a fourantenna six-channel GPS receiver, will provide real-time navigation solutions for orbit trim and raw measurements for ground post-processing, both for more accurate position and velocit...
