Simulation Studies for Improving the Geoid in Egypt
Least squares collocation permits the estimation of the accuracy of predicted quantities such as geoidal heights in dependence on various assumed distributions of heterogeneous data (gravity, GPS, etc.) without needing actual observations (only covariances). In addition to already available data (deflections of the vertical, gravity measurements, Doppler and GPS data), various regularly arranged additional distributions of gravity and / or GPS data were assumed and the resulting accuracy was estimated.
