Knowledge of the shape of the geoid is crucial to accurate use of high precision GPS methods underlying the infra-structure of modern society. Since the shape of the geoid is a product of the earth’s…

The gPhoneX gravity meter has a superlative frequency response; better than seismometers, which were specifically designed for this type of application, which makes it perfect for earthquake studies.

The study of the movements of tectonic plates can be carried out using a relative gravity meters, such as the gPhoneX Gravity Meter or absolute gravimeters such as the FG5-X.

The subsurface distribution of densities has an immediate effect on local gravity anomalies. This is the basis of the gravity method. In such applications, a relative gravity meter such as the CG-6 Autograv™  Gravity Meter…

A zero-length metal spring gravimeter such as the gPhoneX Gravity Meter is best suited for Earth Tide Monitoring because of its low-drift characteristics. Absolute gravimeters such as the FG5-X are also perfectly suited for this…

The long-period monitoring of the Earth’s gravitational field is best done with low-drift zero-length spring gravimeter such as the gPhoneX Gravity Meter or with absolute gravimeters such as the FG5-X.
