Tilt effects on GWR superconducting gravimeters [PDF]

Journal of Geodynamics, 2009
The superconducting gravimeters (SGs) are the most sensitive and stable gravity sensors currently available. The low drift and high sensitivity of these instruments allow to investigate several geophysical phenomena inducing small and long-period gravity changes.
