If all of the above affects the gravitational action on the surface of the Earth, then how is the statement, below, true ? > I expect that in not too many years the official master clocks will no longer > be on Earth, but instead in satellites.

It would seem that the satellite, which is just an arms throw from the surface, would have the same affects acting upon it, albeit perhaps in modified ways. I would think the satellite would have to be placed at the center of the SUN to have all of the effects (within our solar system) reduced to the smallest amount. Can anyone elaborate on this ?
