20.500.12556/RUL-188081 Analiza ponovljivosti koordinat točk v precizni geodetski mreži diplomska naloga Analysis of point coordinate repeatability in a precise geodetic network S pojmom ponovljivosti se v geodeziji pogosto srečujemo. Namen diplomske naloge je analiza ponovljivosti določitve koordinat v precizni geodetski mreži. Opravili smo pet terminskih izmer, med katerimi smo zagotovili enake merilne pogoje ter uporabili enako metodo izmere in instrumentarij. Meritve smo obdelali in mrežo izravnali po metodi najmanjših kvadratov. Sledila sta izračun koordinatnih razlik in premikov. Rezultati so prikazani tabelarično in grafično. Ponovljivost meritev smo ocenjevali na dva načina: z izračunom ponovljivosti na podlagi odstopanj od srednjih vrednosti koordinat ter s statistično analizo premikov. Povprečna ponovljivost, izračunana iz odstopanj, znaša v smeri y 0,11 mm, v smeri x 0,18 mm, položajno pa 0,21 mm. Dobljene vrednosti so primerljive z natančnostjo določitve koordinat, kar je za precizne meritve pričakovano, zato lahko sklepamo, da je ponovljivost dobra. Statistična analiza po klasičnem testu je pokazala prisotnost statistično značilnih premikov pri vseh obravnavanih točkah, medtem ko je analiza na podlagi simulirane porazdelitvene funkcije statistično značilne premike pokazala le pri točkah 4 in FGG3J. Primerjava obeh načinov ocene ponovljivosti kaže na skladnost rezultatov. Metodi se medsebojno dopolnjujeta, saj prva podaja splošno oceno kakovosti določitve koordinat, druga pa omogoča podrobnejšo analizo ugotovljenih odstopanj. Rezultati tako potrjujejo visoko kakovost izvedenih meritev in dobro ponovljivost določitve koordinat v obravnavani geodetski mreži. The concept of repeatability is frequently encountered in geodesy. The aim of this thesis is to analyze the repeatability of coordinate determination within a precise geodetic network. Five measurement campaigns were conducted, ensuring consistent measurement conditions, methods, and instrumentation across all sessions. The measurements were processed, and the network was adjusted using the least-squares method. Subsequently, coordinate differences and displacements were calculated. The results are presented in both tabular and graphical formats. Measurement repeatability was assessed in two ways: by calculating repeatability based on deviations from mean coordinate values and by performing a statistical analysis of displacements. The average repeatability, calculated from these deviations, is 0,11 mm in the y-direction, 0,18 mm in the x-direction, and 0,21 mm in terms of positional accuracy. These values are comparable to the precision of coordinate determination—an expected outcome for precise measurements—leading to the conclusion that repeatability is good. Statistical analysis using a classical test revealed statistically significant displacements at all points under consideration, whereas analysis based on a simulated distribution function indicated statistically significant displacements only at points 4 and FGG3J. A comparison of the two assessment methods shows consistent results. The methods complement each other: the first provides a general assessment of the quality of coordinate determination, while the second enables a more detailed analysis of the observed deviations. The results thus confirm the high quality of the measurements performed and the good repeatability of coordinate determination within the geodetic network under consideration. diplomske naloge gradbeništvo geodetska mreža geodetske meritve posredna izravnava po metodi najmanjših kvadratov analiza ponovljivosti statistično značilni premiki graduation thesis civil engineering geodetic network geodetic measurements indirect least-squares adjustment repeatability analysis statistically significant displacements true false false [T.
