For high precision Geodesy at the end of this century, a precise knowledge of the tidal deformations of the earth’s surface is essential in particular to carefully correct gravity and distance measurements. Absolute and field differential gravity determinations have now about the same precision, that is 10 microgals (1 μgal = 10-8 m s-2) or better in some cases.
