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 ...

Društvo metrologa je formirano u cilju objedinjavanja aktivnosti svih metrologa, pružanju pomoći prilikom njihovog rada i međusobne razmene iskustava.
Misija Društva metrologa je da okuplja i podstiče stručnjake koji ...
Коришћење UAV фотограметрије и ласерског скенирања из ваздуха (LiDAR) приликом праћења активности клизишта на Умци
(Универзитет у Београду - Факултет безбедности, 2023)
Клизишта, као природне непогоде, егзистирају годинама, па у неком случајевима и више деценија. Због штетних последица које проузрокују, а како би се потенцијална опасност благовремено уочила и на време спречила, потребно ...
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 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 ...
Одређивање мерне несигурности резултата мерења просторног растојања применом глобалних навигационих сателитских система / Determination of spatial distance measurement uncertainty using global navigation satellite systems
(Друштво метролога, 2022)
Постоје четири у потпуности успостављена Глобална навигациона сателитска система (ГНСС): амерички GPS NAVSTAR, руски GLONASS, кинески BEIDOU (COMPASS) и европски GALILEO. Њиховом применом успешно се успостављају терестрички ...
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, ...
Ocena pomeranja inženjerskih struktura u programskom paketu PANDA
(Savez inzenjera i tehnicara Srbije, 2022)
U radu se opisuje ocena značajnosti pomeranja tačaka deformacione strukture (objekta) geodetskom metodom deformacione analize. Saglasno unapred pretpostavljenom pomeranju strukture, u dva različita plana merenja, simulirani ...
Influence of the solar hydrogen Lya line on the GNSS signal delay in the ionospheric D-region
(Astronomical Institute of the Slovak Academy of Sciences, 2022)
Recent research indicates that the influence of the ionospheric D-region on the propagation of satellite signals cannot be ignored during the intense X-radiation emitted during solar X-ray flares. In this paper, we investigate ...
