   Abstract : In order to be able to use the operational Moldavian GNSS Positioning System MOLDPOS efficiently for the determination of normal heights in surveying engineering, e.g. during the construction of a road, an accurate quasigeoid model is needed. READ MORE

4. 2. A height datum for Uganda based on a gravimetric quasigeoid model and GNSS/levelling

   Author : Ronald Ssengendo; Lars Sjoberg; Anthony Gidudu; Hossein Nahavandchi; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geoid model; GNSS levelling; KTH method; Uganda; Uganda Vertical Network; Quasigeoid model; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Abstract : This study is devoted to the determination of a high resolution gravimetric geoid model for Uganda based on the optimal combination of terrestrial and satellite gravity anomalies using the method of Least Squares Modification of Stokes’ formula with additive corrections. Specifically the study investigates the current status of the existing Uganda Vertical Network relative to the requirements of a modern height datum and includes a detailed evaluation and validation of terrestrial gravity data, several digital elevation models and some recent global geopotential models.
