METHOD OF BUILDING SUPPORT GRAVIMETRIC CIRCUIT Russian patent published in 1995 - IPC

FIELD: geophysical survey. SUBSTANCE: measurement are carried out at reference points by means of group of gravimeters which operate at forced modes being different for each gravimeter. Measurements are not correlated. Support circuits may be created by routes with unlimited duration. Precision of values measured Δq is defined from relation , where N is number of points in route, for which additional measurements are available; K is degree of polynominal which approximates shift in zero-point; σ is root-mean-square error of single measurement. EFFECT: improved precision; reduced expenses; reduced number of routes. 1 dwg
