Title: TRANSFORMATION OF THE TRANSIT (DOPPLER) AND GPS STATIONS TO ADINDAN DATUM
Author: Elgizouli Mohamed Ahamed, Abd Elrahim; AbdEllatif Abdalla, Kamal
Abstract: Seventeen control points given on the World Geodetic System 1984 (WGS84) and Adindan datum are used to determi ne transformation parameters between WGS84 and Adindan datum. Using Doppler stations on Adindan datum ,and the transformation parameters of Doppler satellite datum (WGS72) and Adindan , differences in parameters between t he datum of GPS(WGS84) and Doppler (WGS72) were computed. These differenc es are not properly equal to that adopted by USA Defense Mapping Agency (DMA). This is due to erroneous reductions of measured distances to the Clark 1880 ellipsoid, and to the fact that geoid heights were not known perfectly.
