Hi Horace, I don't deny that gravimagnetism exists (it's an obvious consequence of gravity propagating at a finite speed, if the term means what I think it means i.e. the gravitational Lorentz force) but when you say "the ambient gravimagnetic field in the vicinity of Earth required to account for the precession of the Earth", are you suggesting the observed precession rate is not, or not entirely, accounted for by the official explanation that this precession is due to the gravitational torque exerted by the Sun on the Earth's equatorial bulge?
http://en.wikipedia.org/wiki/Precession_of_the_equinoxes#Explanation The official theory works nicely though, I remember I had to derive the precession rate as a physics exercise when I was a student many years ago, assuming the Earth was an homogeneous ellipsoid of the right dimensions, and it came out strikingly close to observations.

Do you know? > > Hoyt Stearns Pioneer 10 is heading toward Aldebaran in Taurus. Pioneer 11 is headed toward Aquila (The Eagle), northwest of the constellation of Sagittarius. The galactic center is located in the direction of Sagittarius, so Pioneer 11 is headed in its general direction, but way north of it. The galactic center is located near the radio source Sagittarius A*, which is located at 17h45m40.04s −29°00′28.1″, about 29 degrees below the ecliptic. Taurus is away from the Sagittarius, so Pioneer 10 is headed away from the galactic center. By calling the ambient gravimagnetic field "galactic" I did not mean to imply the galactic center is the source of the ambient gravimagnetic field. In fact, I wrote in: http://www.mtaonline.net/~hheffner/SolarLunarGK.pdf "The cumulative gravimagnetic field of the sun and moon do not come within 11 orders of magnitude of the ambient gravimagnetic field in the vicinity of Earth required to account for the precession of the Earth." "Momentarily ignoring the many possibilities for error, this leads automatically to the wild speculation that we have a powerful unseen spinning neighbor that has been around for a long time, longer than the solar system. The plane of the solar system (the ecliptic) is not aligned with the plane of the Milky Way, so it is unlikely the galactic core is involved. The axis of precession is aligned with the poles of the ecliptic, thus the ambient gravimagnetic field must be also, on average. We may have a dark partner in our part of the galaxy." "If the dark partner were 150 light years away it would have to have [(1.551 x 10^-11 i Hz)/(9.526x10^-23 i Hz)]/(150 ly/1.496x10^8 km)^3 = 1.39x10^32 times the gravimagnetic dipole moment of the sun."
