Hungarian Gravimetric Network

Responsible: András KOPPÁN Ph.D.

Based on the law LXXVI/1996 (about „Land-surveying and cartographic activity”) the base points of Hungarian Gravimetric Network are state-owned base points and those works concerning the maintenance of the network are governmental works. The maintenance includes the following activities: the systematic supervision of the 465 base point of the network, the reinstallation and measurement of destroyed base points, calibration of relative gravimeters and keeping up-to-date the digital point catalogue.
The Hungarian Gravimetric Network (HGN) –like any other geodetic base network – has double duty. It provides reference gravity values for the gravimetric field measurements and the local geoid determination.
