(a) procedure to measure the vertical gravity gradient indicating the measurement progression from 1 to 11 at different heights from the ground (Step#1 = about 15 cm; Step#2 = about 45 cm; Step#3 = about 70 cm; Step#4 = about 125 cm); (b) The Scintrex CG-6 relative gravimeter during vertical gravity gradient measurement; (c) scheme of the connection to calculate the gravity difference (Δg) between the indoor absolute point with one or more outdoor satellite station/s using the CG-6 Scintrex relative gravimeter.
