<p>Vertical Control Networks are critical in establishing Geodetic Reference Frames at both local and regional levels. The fundamental inputs for propagating geopotential differences, which help determine physical heights essential for the vertical components of these frames, are geometric leveling and gravity observations. In this study, we apply orthometric and normal corrections to the Vertical Control Network of Ecuador to obtain height differences that account for the effects of gravity. Since not all level references within the Vertical Control Network have corresponding gravity observations, we derive gravity values for calculating orthometric corrections through interpolation and Global Geopotential Models. Finally, we analyze the results by calculating the misclosure errors of the network loops. This analysis considers the impact of orthometric and normal corrections and variations in the gravity sources.</p>
