Evaluation of global earth gravity models and corrector surface techniques for GNSS/leveling-derived geoid fitting in Ethiopia

Abstract The establishment of a reliable vertical reference framework remains a fundamental challenge in geodetically complex regions such as Ethiopia, where extreme topographic gradients and lithospheric heterogeneity severely compromise the predictive accuracy of Global gravity models (GGMs). This study presents a hy...
