METHOD OF ADJUSTMENT OF AIRBORNE GRAVITY GRADIOMETER Russian patent published in 1995 - IPC

FIELD: gravimetry. SUBSTANCE: procedure of measurement of six components of tensor of second derivatives of gravitational potential and compensation of methodical and instrumentation errors caused by drift of zero, gravitational interference from masses of airborne carrier and their redistribution as well as by influence of systematic destabilization factors in its legitimate signal is improved. During movement of airborne carrier in processing of signals proportional to measurement vector signals of accelerometers are summed up with signals proportional to values of integral of second derivatives of gravitational potential coming from output of gradiometer. There are also used increments of spatial coordinates of airborne carrier for specified interval of integration time fed from computer of flight navigational complex which signals are also proportional to present values of navigational and kinematic parameters of airborne carrier. EFFECT: improved measurement procedure. 6 dwg, 1 tbl
