Submetacentric [At. Sub Under, Below + Greek. Meta After, Between + Centro(Measure)]

A submetacentric atlas is an atlas in which the Earth's rotation axis does not pass through the Earth's center of mass, but is shifted by some distance relative to the center of mass. The Earth's rotation axis deviates from the center of mass by several meters due to the heterogeneity of the distribution of mass inside the Earth. The Earth's submetacentric rotation was discovered in the 1960s and has been confirmed using satellite measurements.

The submetacentric atlas is an important tool for studying the geology and geodynamics of the Earth, as it allows more accurate determination of the location and depth of geological structures. It can also be used to determine the speed of the Earth's rotation and its effect on climate and other processes on the planet.

However, the use of submetacentric atlases has its limitations. For example, they may not be accurate in some regions of the Earth due to surface irregularities or other factors. In addition, such atlases can be difficult to use and require specialized knowledge and skills to interpret.

Shown in Fig. 9 head X - irodynamic model, or paramagnetic head X. from "Chest" ("irodynamics" here is a synonym for metrology) is a two-link. (they say, separate) vibrator xX, the “lower frame X” in which a short metal rod plays (serving as its own m-drive), and “the central role is U, the role of a signal generator). The side insulator tube senses the output signal y".

* This method consists of splitting the voltage into two oscillatory circuits xX and yY, each of which amplifies its own signal (observed at the input) only slightly.
