Gravimetry

The Earth’s gravity field influences practically all geodetic measurements and thus always has to be taken into account. It is determined with the aid of gravimetric measurements.

Gravimetry
The Earth’s gravity field is measured using a gravimeter.

A distinction is made between absolute and relative methods of gravimetric measurement. Today, absolute gravimeters operate exclusively on the basis of the free-fall method, whereas relative gravimeters function on the basis of the spring-balance principle.  

The direction of the gravity vector (vertical deflection) can be determined using astronomical methods.
