Full tensor gravity gradiometry (FTG) (not to be confused with gravimeter) is a technology of gravity field volumetric imaging that allows to detect density changes in the materials that make up the surrounding space. The result of such imaging is a three-dimensional model describing the substances in the object of study.
The technology is based on the fact that any physical object has a gravitational field that contributes and leaves a trace in the structure of the Earth's gravity field. The trace of each object is unique and depends on its location, shape, size and density. A volumetric imaging of the gravity field makes it possible to identify the objects that form it. In effect, it is a new way of perceiving space, that is more advanced and informative than vision and echolocation.
The development of gravity gradiometry technology is of no less significance than the invention of the camera image sensor, without which it would be difficult to imagine the modern world.
Gravity gradiometry opens up qualitatively new possibilities in many areas. For example, in navigation it makes system independent from satellites and radio signals, and in the field of mineral exploration it greatly simplifies the process of exploration and can work in conditions where other methods cannot be used.
