Since the early 1990s, GFZ has been operating superconducting gravimeters for high-precision, long-term stable and continuous monitoring of temporal gravity changes. These are the integral effects of all mass variations and deformations induced by a large number of geophysical effects on a wide spectrum from seconds to decades.

GFZ currently operates superconducting gravimeters at the following five observatories in Germany:

• Zugspitze
• Helgoland
• Eifel (CVO Eifel)
• Serrahn (TERENO-Northeast)
• Buro

They are part of the International Geodynamics and Earth Tide Service (IGETS) with the IGETS database operated at GFZ.
