For the computation, Global Geopotential Models (GGMs) such as EIGEN-6C4, GECO, GOCO05c, and XGM2016 were applied for degree and order 100 and 200. The Least Squares Collocation (LSC), Stokes' Integral, and Hotine's Integral were the methodologies selected in this study. The results were validated in terms of geopotential values, normal heights, and height anomalies. The values obtained present more consistence for the integration radius up to 2 degrees. Moreover, LSC and Hotine's integral showed convergence in the results.engGeopotential modelsgravityInternational Height Reference Frame (IHRF)Artigo10.1109/LGRS.2021.30712542-s2.0-85104574849
