| الملخص (بالإنجليزية): |
In this work the results of research of geopotential models at the teritory of Republic of Croatia are presented. In phase 1 of this research all models in 15'x15' grid have been used and EGM96 has been chosen as referent. The differencies between height anomalies of EGM96 and other models had been calculated. It has shown that Eigen-cg01c model had the least deflection from EGM96. In phase 2 of this research 138 GPS-levelling points with known geoid undulations have been used to interrogate which of models best fits values of geoid undulations at GPS-leveiling points. It has shown that the minimum standard deviation of differences has Eigen-gl04c model (σ = ±0.316 m). [ABSTRACT FROM AUTHOR] |
| Abstract (Croatian): |
U radu su prikazani rezultati ispitivanja globalnih geopotencijalnih modela na području Republike Hrvatske. U prvoj fazi ispitivanja koristili su se modeli u rasteru 15'x15', u kojem se EGM96 uzeo kao referentni model. Izračunate su se razlike geoidnih undulacija između EGM96 modela i ostalih modela. Pokazalo se da Eigen-cg01c model najmanje odstupa od EGM96 modela koji je ujedno i najuglačaniji. U drugoj se fazi upotrijebilo 138 GPS-nivelmanskih točaka s poznatim undulacijama i ispitalo se koji od modela u egzaktnim točkama najbolje odgovara vrijednostima GPS-nivelmanskih undulacija. Ispostavilo se da je minimalna standardna devijacija odstupanja najmanja kod Eigen-gl04c modela (σ - ±0.316 m) [ABSTRACT FROM AUTHOR] |
