Absolute Gravimetry

Small changes in height cause detectable differences in the strength of the gravitational field experienced by a falling object.


The purpose of running an AG at the SGF Herstmonceux is to provide a long-term data set which can provide vertical height movements independent of those from the space based geodetic techniques. A long-term aim is to investigate the Global Isostatic Adjustment (GIA) signal from this region.

AG data has been collected at Herstmonceux since 2006 and it has been shown that there are signals within the data which are of interest and should be removed. The signals detected are on various time scales and from various of sources. Investigations are being carried out on tidal, atmospheric and hydrological responses.
