On the impossibility of measuring the general relativistic part of the terrestrial acceleration of gravity with superconducting gravimeters

In this paper we very preliminarily investigate the possibility of measuring the post-Newtonian general relativistic gravitoelectric and gravitomagnetic components of the acceleration of gravity on the Earth, in continuous regime, with two absolute measurements at the equator and the south pole with...
