METHOD FOR ABSOLUTE MEASUREMENTS OF A GRAVITATIONAL FIELD ON A MOBILE OBJECT Russian patent published in 2019 - IPC G01V7/16 

FIELD: geophysical survey.

SUBSTANCE: invention relates to geophysical research and can be used to find small anomalies of gravity in marine measurements. Technical effect is achieved due to the fact that two absolute gravimeters are fixedly installed on object in points with known distance between them, accelerometers with horizontal axes of sensitivity are installed in same points, in signals of gravimeters and accelerometers, the second harmonic of oscillations of object rolling is selected, from which vertical components of translational acceleration of rolling are calculated, which are subtracted from signals of gravimeters, obtained after subtracting translational acceleration of angular rolling signals of gravimeters are added and subtracted, obtaining signals of sum and difference, from distance between points of installation of gravimeters and speed of movement of object determine the time required for overcoming this distance and calculating the phase shift of the orbital motion which occurred during that time, substituting the phase shift in the difference signal, calculating the orbital motion parameters, subtracting the orbital motion acceleration signal from the sum signal and obtaining the instantaneous acceleration of gravity, which is averaged.

EFFECT: high accuracy of measuring gravity on a mobile object, high efficiency of measuring gravitational field and accuracy of navigating thereon.
