The Gravimetric Station of Brasimone

From 1990 up to now a superconducting gravimeter GWR model TT70 is operating in a laboratory located on the dismissed nuclear power plant of Brasimone, in the italian Apoennines between Bologna and Florence, in the frame of an experiment meant to verify Newton's gravitational law. From july 1995, the gravimeter is involved in the Global Geodynamics Project, and is actually working for high precision tidal analysis and modelling. In this paper we describe the calibration procedure adopted together with the preliminary results of the tidal analysis performed using yhe software Eterna 3.20.
