Abstract

This paper demonstrates how the height of the geoid above the reference ellipsoid can be computed from surface gravity observations with high local precision. The geoid is the equipotential surface, closely approximated by mean sea level, which forms the zero-reference for conventional measurements of topographic height. The Global Positioning System (GPS) can measure the height of a ground-based receiver above the reference ellipsoid with a precision of a few centimetres. Consequently, a combination of GPS measurements with a precise gravimetric geoid can provide a cheap alternative to nationwide geodetic levelling.
