DMA Support to a Unified Geodetic Datum for the African Continent

Abstract

This paper recounts the conventional geodetic accomplishments of the Defense Mapping Agency (DMA) and its predecessor organizations in Africa, beginning with the 30th Meridian Arc in the early 1950's and continuing through the 12th Parallel Survey, which was completed in 1970. Additionally, it identifies the modernization resulting from the many Doppler geodetic positions, referenced to DMA's precise Navy Navigation Satellite ephemerides, established to date throughout the continent. Further it provides a conceptual plan for accomplishing, through bilateral agreements with the countries involved unification of the African datum by means of future efforts of Doppler data acquisition and reduction/adjustments of geodetic control.
