First epoch measurements of absolute gravity were made at the Grant Institute at Edinburgh University and the Hydrographic Office at Taunton. These data, together with the POL data and an earlier, less accurate, measurement at the National Physics Laboratory at Teddington have already been used to constrain the British Precise Gravity Network (1993).

The Department of Geology and Geophysics at Edinburgh Universtity have continued to assist the project by determining local gravity gradients and local gravity transfers.

The very accurate gravity difference now established between HO Taunton and POL is routinely used by the Hydrographic Office to recalibrate and check the gravimeters carried on board their survey vessels and to establish gravity values of use to the Royal Navy.

In December the absolute gravimeter was returned to the United States for a "refit". The gravity values determined before and after this refit indicate no observable shifts in the gravity datum, reinforcing our confidence now in the values of gravity obtained.
