On the characteristics and potential facilities of the sensitive unit of the GT-2A gravimeter

Characteristics of the sensitive unit of the aerogravimetric complex GT-1A (GT-2A) are examined on the basis of experimental material obtained during aerogravimetric surveys. The stability of the zero-point drift of this sensitive unit, the function of the approximation of zero-point drift, the stability of the initial indications on a particular airdrome reference point and the correspondence between the difference in initial readings at different airports and that of gravitation acceleration values according to the first-order State gravimetric network data are discussed.
