The prototype was developed at the Istituto di Fisica dello Spazio Interplanetario (IFSI) of the National Institute of Astro-Physics (INAF). The gravimeter acquired with a sampling rate of 1 Hz.</p> <p><b>Purpose:</b> The instrument performs measurements of the Earth gravity acceleration due to low ground movements (tides) and fast ground movements (seismic wave propagation).</p> <p><b>Quality of data:</b> Systematic noise lasting for 5 seconds is present at start of each daily file due to the midnight clock synchronisation. The 247 daily text files are stored in a folder of 749 MB. In general the gravimetric data shows a good recording quality.</p>
