METHOD AND DEVICE FOR REMOTE GRAVIMETRIC PROBING Russian patent published in 2016 - IPC G01V7/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to geophysics and is intended for determination of free fall acceleration g_z and its spatial characteristics g_φ both on Earth surface and on surfaces of other planets. For determination of free fall acceleration g_z and its spatial characteristics g_φ use is made of a measuring device equipped with a zero-indicator sensor and gradient sensors installed on a disc located in the positioning device with a possibility of rotation. Method of performing a gravimetric probing consists in obtaining, with the help of a measuring device of a 3D time plot g_φ and comparing of the obtained time plot with “normal time plot” in order to detect an abnormal area on the 3D-time plot. This method provides for a possibility to obtain a volumetric characteristic of the gravitational field; at that, the range of measured values of gravitational acceleration is not limited.

EFFECT: technical result of the alleged invention consists in the improvement of accuracy and informativity of gravimetric measurements.
