Determination of ionospheric models using global navigational satellite systems and Bernese GNSS software
(Faculty of Civil Engineering, University of BelgradeInstitute of Physics Belgrade, University of Belgrade, 2023)
Since the last few decades of the 20th and the beginning of civilian application of NAVigation Satellite Timing And Ranging Global Positioning System (NAVSTAR GPS) established by the United States Department of Defense, ...
Designing and Realization of the Control Networks of the Telecommunication Tower Avala
(САВЕЗ ИНЖЕЊЕРА И ТЕХНИЧАРА СРБИЈЕ, Београд, 2020)
The Avala telecommunication tower was destroyed during the NATO bombing in 1999. The construction of the new tower at the same place started in 2007. The new tower consists of reinforced concrete part, with a total height ...
Space-time high-resolution data of the potential insolation and solar duration for Montenegro
(Institut za argitekturu i urbanizam Srbije, 2020)
The assessment of the potential use of renewable energy resources requires reliable and precise data inputs for sustainable energy planning on a regional, national and local scale. In this study, we examine ...
Agricultural Land Use Changes as a Driving Force of Soil Erosion in the Velika Morava River Basin, Serbia
(MDPI, 2023)
The erosion potential model was applied to estimate the soil erosion status of rural settlements during the years 1971 and 2011. We used univariate and bivariate local Moran’s I indices to detect and visualize the spatial ...
Doprinos određivanju jonosferskog kašnjenja GNSS satelitskih signala na teritoriji Republike Srbije
(Savez inženjera i tehničara Srbije, Beograd, 2023)
Višefrekvencijski GNSS satelitski signali i njihova dostupnost omogućavaju istraživanja u nediferenciranom i nekombinovanom modelu u kome je pojedinačni signal na svakoj frekvenciji odgovarajuće nezavisno opažanje. Ovakve ...
Comparison of IRI-2016 and NEQUICK models of the ionosphere over the Balkan Peninsula during the year 2019 / Поређење IRI-2016 и NEQUICK модела јонофере изнад Балканског полуострва током 2019. године
(University of Banja Luka, Faculty of Architecture, Civil Engineering and Geodesy, 2022)
In this paper, a comparative study of the total vertical electron content (VTEC) calculated using the IRI-2016 and NeQuick2 models were performed. The research was done for the days of maximum solar activity in 2019, with ...
GNSS signals as a tool for detection of the influence of solar radiation of terrestrial ionosphere
(IV Meeting on Astrophysical Spectroscopy - A&M DATA - Atmosphere, BOOK OF ABSTRACTS AND CONTRIBUTED PAPERS, 2022)
Solar radiation has the most significant influence on photo-ionization in the
Earth's ionosphere, and different parts of its spectrum in the UV and X domains
have a dominant role in producing free electrons at different ...
Field procedure for estimation of antenna phase center variation with expanded measurement uncertainty calculation
(University of Montenegro, Faculty of Civil Engineering, 2022)
Antenna phase center of GNSS receiver is the point where the signals transmitted from satellites are collected. However, this point is not necessarily the physical center of antenna (geometric center of antenna). In general, ...
Evaluation and tailoring of global geopotential models in the determination of gravity field in Serbia / Оцена и тејлоровање глобалних геопотенцијалних модела при одређивању гравитационог поља на територији Србије
(Међународна научна конференција ''Савремена теорија и пракса у градитељству XIV”, 2020)
Within this paper, we evaluated the quality of three Global Geopotential Models entitled: EGM96,
EGM2008, and GOCO05c. The models were evaluated by using 1001 terrestrial discrete values of height anomalies determined by ...
Permanent GNSS monitoring of landslide Umka
(University of Banja Luka Faculty of Architecture, Civil Engineering and Geode, 2020)
The Umka landslide is one of the biggest inhabited active landslides in Serbia. The Umka landslide activity has been monitored for a period longer than 85 years, by various geotechnical and geodetic techniques. Since 2010, ...
