A discussion of gravimagnetism and the Pioneer Anomaly is located at
the end of:

It is proposed that the Lorentz force from the ambient gravimagnetic
field of the galaxy is the primary underlying cause for the Pioneer
Anomaly.
Yesterday I noticed that there was a problem with the sign of the
force expected on the Pioneers. It finally dawned on me that the
ambient gravimagnetic force can be either North to South or South to
North and create exactly the same earth precession. The Pioneers
then let us determine the direction of ambient gravimagnetic field.
It is just the opposite of what I had assumed before this realization.
The orientation of the ambient galactic gravimagnetic field is thus
towards the North Ecliptic Pole in Draco, coming from the South
Ecliptic Pole. Another vortex first (I hope!)
The article above has been updated to reflect this realization.
