In quite precise language, Einstein taught that the centrifugal force on an object in the earth's rest frame (the condition satisfied by the hovering geosynchronous satellite) is inadmissible as evidence of the rotation of the earth, for in the earth's frame that force arises from "the average rotational effect of distant, detectable masses."

Equally in GR this force is inadmissable as evidence that the universe is rotating and the earth is static. Both frames are as valid as each other. So this advances neither the heliocentric nor the geocentric argument.
