“…Pessimistic internal estimates give an absolute accuracy of ±8cm, which may reduce to ±1cm over 100km [22]. Comparisons of OX92 with GEOSAT satellite altimeter data in the western North Sea indicate its precision as ±3cm in the 20-700km range [74]. However, this error estimate will probably increase on land due to topographic effects.…”

The history of published geoid determination for the British Isles over the last fifty years is reviewed. This includes global geopotential models, tailored geopotential models, British gravimetric geoid models, and European gravimetric geoid models that cover the British Isles. Proposals are made for a collaborative venture to produce a new geoid model using the most recent data and computational techniques.
