The aim of this diploma thesis is to analyze the geodetic control network at Melje, a small hydroelectric power plant, with emphasis on the effect of the geodesic grid on the power plant's accuracy. The primary interest is which type of network would be optimal for measurement. We hypothesize that it would be a combined or constrained geodetic network. Initially, there's a description of the power plant and its associated network, followed by the description of the stabilization and signaling of the individual nodes. Subsequently, we take a look at the method of measurement along with the geodesic equipment used and the method of calculation. The latter begins with the preparation of raw observations, proceeds with the reduction of distances, horizontal directions, and zenith distances. It ultimately concludes with the adjustment of the vertical and horizontal geodetic network. Throughout the thesis, we also present the necessary conditions for a well-established geodesic network on a hydroelectric power plant and the expected accuracy of such a network. In the results section, we present and describe the geodesic grid's variations more accurately as well as arguments for their accuracy. The results are displayed in a graphical format using an error ellipse and are also summarized in a table. In the conclusion, we focus on summarizing the findings and revisit the given hypothesis. The hypothesis is then argued, evaluated, and ultimately confirmed.
