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, ...
Nove karte gravimetričnih anomalij na območju Republike Slovenije
(Slovensko združenje za geodezijo in geofiziko, 2022)
Obstoječa karta Bouguerovih anomalij, ki pokriva ozemlje Republike Slovenije, je stara nekajdesetletij. Od takrat je na voljo kar nekaj novih podatkov o merjenem težnostnem pospešku naobmočju Slovenije, ter kakovostnih ...
The impact of the Atmospheric Parameters at Electrooptical Distance Measurements
(International Federation of Surveyors, FIG, 2022)
The electro-optical distance measurement (EDM) instruments are widely used not only in geodesy but also in almost all engineering disciplines and related projects. High accuracy length measurements are required especially ...
Influence of the periodic changes in the incoming solar hydrogen Ly-α radiation intensity on the total electron content in the ionospheric D-region
(2022)
This paper analyzes variations in the total electron content in the D-region induced by periodical changes in the solar hydrogen Lyα radiation. The considered changes are a consequence of variations in the solar radiation ...
Generalized habitat map of Serbia
(14th Symposium on the Flora of Southeastern Serbia and Neighboring Regions, 2022)
The generalized habitat map of Serbia is one of the products of the project carried out for the needs of the Institute for Nature Protection of Serbia by the Faculty of Biology University of Belgrade in cooperation with ...
Influence of Given Parameter Errors on Accuracy of Tunnel Breakthrough by Height
(Contributions to International Conferences on Engineering Surveying, 2020)
There are two types of geodetic 2D and 1D networks for tunnel construction: overhead and underground. The purpose of these networks is to perform tunnel stake out with allowable deviation in transverse, longitudinal and ...
Within-field correlation between satellite-derived vegetation indices and grain yield of wheat
(BioSense Institute, Novi Sad, 2021)
This research aimed to inspect the correlation coefficients, during the crop growth stages, between vegetation indices (VIs) derived from Sentinel-2 imagery and grain winter wheat yield derived from yield monitoring and ...
Classification of irrigated and rainfed croplands in Vojvodina Province (North Serbia) using Sentinel-2 data
(2021)
In the 21st century, the establishment of efficient water resource management is crucial for ensuring world water and food security. Irrigation is a significant artificial process in the hydrological cycle and presents the ...
