AB  - Geodetic monitoring of a tall structure means employing various methods of measurement and data processing for assessing its verticality. Terrestrial laser scanning (TLS) is a method of collecting lots of quality spatial data in a short time period. It enables detailed surface 3D parametric modelling. Advantages over the traditional cross-sectioning approach include direct obtaining of the structure axis inclination, analysing structure deformations relative to the modelled surface, and so forth. The subject of research was 52-metre-tall cylinder-shaped bell tower of St. Anthony of Padua Church in Belgrade, Serbia, which has been inclined since its completion in 1962. An original algorithm was developed for estimating parameters of a cylinder approximating the tower surface and their precision. The horizontal displacement of the cylinder top base centre ranging from 1.174 m to 1.196 m over the five-year period of geodetic monitoring of the tower indicates the clear existence of the structure tilting trend.

AB  - Results of recent monitoring activities conducted from 2014 to 2019 are presented in the paper as a part of IPL 181 Project progress report. Recent monitoring activities are concentrated on several landslide monitoring techniques— automated GNSS monitoring system measurements, geodetic benchmark survey monitoring, UAV imaging, processing and analysis, and PSInSAR data processing and analysis. Results of all monitoring activities were analysed and used for cross-correlation and for verification of monitoring results obtained from different techniques. Displacement rates from GNSS measurements indicate that object point UmkaGNSS2 has moved 0.30 m towards the North and 0.50 m towards the West, while the vertical displacement was approximately −0.15 m for the 2014–2018 time span. Similar range of GNSS displacement rates were found in previously published results from monitoring activities realized from 2010–2014. PSInSAR data analysis also showed good correlation between nearest PS points and GNSS point for the same period of monitoring. Results from UAV and geodetic benchmarks survey showed very good correlation in displacement vectors’ direction. According to the analyzed data it could be concluded that all monitoring results are in compliance with previous research results and confirm that the Umka is slow tovery slow moving landslide with cyclic acceleration and deceleration phases.

AB  - 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, landslide activity has been continuously monitored by automated permanent Global Navigation Satellite System (GNSS) based monitoring system in real time. Furthermore, since 2018 landslide activity has been monitored by GNSS kinematic positioning of a set of characteristic points as well as by UAV (Unmanned Aerial Vehicle) photogrammetry. The main issue of this paper is the presentation of the results gained with GNSS kinematic positioning of characteristic points of Umka landslide within three observation epochs.

AB  - 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 height terms. Overhead network is developed before a tunnel is built and it connects entry and exit portal into a unique system. Underground network expands during tunnel construction. When evaluating the coordinates of newly assigned underground network points, previously established points are considered as given points. In
order to realistically estimate the accuracy of underground network, it is necessary to include all previous measured quantities in the adjustment, and to define a minimum trace at all points. With this approach, estimated coordinates of network points would change each time when network is extended. To avoid this problem, when estimating new points, errors of given parameters must be taken into account. In the example of the Tunnel Vežešnik in Montenegro, when designing a 1D underground network, a case was reviewed when previously established points were taken as given and when their error was considered. To validate this procedure, an accuracy calculation was applied only when the overhead network points were defined as given. The network quality criteria were compared for all cases and it was shown that errors of the given parameters must be taken into account.

AB  - Unlike traditional methods, terrestrial laser scanning (TLS) enables one to collect enormous amount of data in a fairly short time, consequently reducing field efforts. This backed up the decision to employ TLS for deformation monitoring of the brick bell tower of St. Anthony of Padua Church in Belgrade. One epoch of terrestrial laser scanning completed in March 2015 revealed that the projection of the tower axis vector to the horizontal plane reached the value of almost 1.2 m, that is nearly three times greater than the value observed at the time of the tower completion. This urged for the tower stability monitoring to be started which finally happened in 2019. Over a period of about four and a half years a trend in the tower tilting increase of 1.6 arcmin in total was unequivocally established, that is, the top of the tower displacement of 22 mm in the horizontal plane.

Special attention has been paid to the establishment of the modern network using Global Navigation Satellite Systems (GNSS). Within the networks established by GNSS, two last realised networks are especially distinguished. The first one is a classic spatial reference network SREF (Serbian Reference Frame) established in 2003, and the second one is a permanent stations network - AGROS (Active Geodetic Reference Network of Serbia) realised in 2006.

AB  - To understand general ionosphere properties over Serbia, an analysis of temporal and spatial ionosphere Total Electron Content (TEC) over the region was performed. The present research focuses on daily, seasonal and spatial ionosphere variations, based on TEC series calculated from the GNSS ie. GPS measurements. This analysis provides for characterization of ionosphere nature and fine structure over Serbia, both locally and regionally. For the days with high solar activity changes of TEC values ranges from minimum 4 Total Electron Content Units (TECU), in night hours, up to 55 TECU around the noon. It is shown that that changes are equivalent to the to the delay of GPS signals approximately 8.8 m in in vertical direction during the (maximum) daily conditions and the delay of 0.6 m during the (minimum) night conditions. Also, it is shows that a seasonal TEC differences follows directly Son activity during the seasons, and maximal differences of TEC values between the seasons reaching values of 45 TECU, again in the years of high Son's activities. For spatial changes all gained results indicate that there exist changes in all directions which cannot be recognized as constant bias or a trend.

AB  - This paper presents determination of height anomalies by the means of Global Geopotential Model 2008 (EGM08). Height anomalies were determined at 1073 points over the territory of Serbia, with known discrete values of height anomalies, which were also determined by satellite leveling. For each of the points, cumulative results of determination had been archived during the calculation for each degree, from 0 to 2190, thus 2191 results of determination were at the disposal for a point. The results obtained were compared with the discrete height anomaly values, and it was concluded that the highest quality of approximation for the discrete undulation values is being achieved using only coefficients up to 1181st degree, thus the present paper shall designate it: the optimal degree.

Using the model of Gravity Observation Combination 02S and 03S (G00002S and GOCO03S) with three different approaches (space-wise approach, time-wise approach, and direct approach) as well as the model of the Earth Gravitational Model 2008 (EGM08) and Earth Gravitational Model 1996 (EGM96) the anomalies of free air at 1293 points of gravimetric survey of Montenegro were determined; as well as the height anomalies at 46 points for which the discreet values of height anomalies are known. The discreet values of height anomalies were calculated as differences between orthometric heights, determined by high precision levelling and the ellipsoidal heights determined by the global positioning system (GPS/dh); and at the points of gravimetric survey of Montenegro, the free air anomalies related to the Geodetic Reference System 1980 (GRS80) and to the International Gravity Standardization Net 1971 (IGSN71) were determined. The data used in this paper are the data of gravimetric survey of former Socialistic Federative Republic of Yugoslavia, and the data of the height anomalies discreet values are data collected in March 2015 for further scientific research, particularly for geoid/quasigeoid determination for Montenegro.

AB  - This paper presents geometrically and physically defined height systems, along with their evaluation by the means of Global Navigation Satellite Systems (GNSS) and Global Geopotential Models (GGM). The paper defines ellipsoid heights as an instance of geometrically defined heights; with physically defined heights being represented by definitions of orthometric and normal heights. Methods of normal heights calculation by the means of ellipsoid heights are presented in detail, as determined using the GNSS and height anomalies calculated from the
GGM application. Apart from the above, numerical part of the paper evaluates normal height values and compares them to their conditionally accurate values at 1073 points with relatively uniform distribution over the entire territory of Serbia. Conditionally accurate values had been determined by the means of classical geodetic terrestrial methods. Under the procedure of evaluating normal height values, GGM – GGM05C was used, as created in 2016 by the Center for Space Research, University of Texas at Austin. In order to evaluate the quality of applying the
model above, data on normal heights evaluation were also presented, using the GGM EGM96, created in 1996 by the National Imagery and Mapping Agency (NIMA), Goddard Space Flight Center (GSFC – NASA) and Ohio State University, presently being the most commonly used model. The comparison above indicates that application of the GGM05C model provides 50 % greater quality of normal heights evaluations against the ones obtained using the EGM96 model.
AB  - У оквиру рада приказани су геометријски и физички дефинисани системи висина, као и
њихова оцена применом глобалних навигационих сателитских система (GNSS) и глобалних
геопотенцијалних модела (GGM). У раду је дата дефиниција елипсоидних висина као представника геометријски дефинисаних висина, а у погледу физички дефинисаних висина приказане су дефиниције ортометријских и нормалних висина. Детаљно су представљени начини рачунања нормалних висина применом елипсоидних висина, које су одређене применом GNSS и аномалија висина које следе из примене GGM. Поред наведеног у нумеричком делу рада оцењене су вредности нормалних висина и упоређене са њиховим условно тачним вредностима и то у 1073 тачке које су релативно правилно распоређене по читавој територији Србије. Условно тачне вредности одређене су применом класичних
геодетских терестричких метода. У поступку оцене вредности нормалних висина коришћен је GGM GGM05C који је креиран 2016. године од стране Центра за космичка истраживања у Тексасу (Center for Space Research, Univesity of Texas at Austin). У циљу оцене квалитета примене наведеног модела приказани су и подаци оцене нормалних висина при примени GGM EGM96 који је креиран 1996. године од стране Националне агенције за дигиталну обраду слика и картирање (National Imagery and Mapping Agency - NIMA), Центра за космичке летове Националне космичке агенције (Goddard Space Flight Center – GSFC - NASA) и америчког Универзитета Охајо (Ohio State University), који до данас представља најчешће коришћени модел. Из наведеног упоређења следи да се применом модела
GGM05C добијају 50% квалитетније оцене нормалних висина од оних које следе из примене модела EGM96.

abstract = "This paper presents geometrically and physically defined height systems, along with their evaluation by the means of Global Navigation Satellite Systems (GNSS) and Global Geopotential Models (GGM). The paper defines ellipsoid heights as an instance of geometrically defined heights; with physically defined heights being represented by definitions of orthometric and normal heights. Methods of normal heights calculation by the means of ellipsoid heights are presented in detail, as determined using the GNSS and height anomalies calculated from the
GGM application. Apart from the above, numerical part of the paper evaluates normal height values and compares them to their conditionally accurate values at 1073 points with relatively uniform distribution over the entire territory of Serbia. Conditionally accurate values had been determined by the means of classical geodetic terrestrial methods. Under the procedure of evaluating normal height values, GGM – GGM05C was used, as created in 2016 by the Center for Space Research, University of Texas at Austin. In order to evaluate the quality of applying the
model above, data on normal heights evaluation were also presented, using the GGM EGM96, created in 1996 by the National Imagery and Mapping Agency (NIMA), Goddard Space Flight Center (GSFC – NASA) and Ohio State University, presently being the most commonly used model. The comparison above indicates that application of the GGM05C model provides 50 % greater quality of normal heights evaluations against the ones obtained using the EGM96 model., У оквиру рада приказани су геометријски и физички дефинисани системи висина, као и
њихова оцена применом глобалних навигационих сателитских система (GNSS) и глобалних
геопотенцијалних модела (GGM). У раду је дата дефиниција елипсоидних висина као представника геометријски дефинисаних висина, а у погледу физички дефинисаних висина приказане су дефиниције ортометријских и нормалних висина. Детаљно су представљени начини рачунања нормалних висина применом елипсоидних висина, које су одређене применом GNSS и аномалија висина које следе из примене GGM. Поред наведеног у нумеричком делу рада оцењене су вредности нормалних висина и упоређене са њиховим условно тачним вредностима и то у 1073 тачке које су релативно правилно распоређене по читавој територији Србије. Условно тачне вредности одређене су применом класичних
геодетских терестричких метода. У поступку оцене вредности нормалних висина коришћен је GGM GGM05C који је креиран 2016. године од стране Центра за космичка истраживања у Тексасу (Center for Space Research, Univesity of Texas at Austin). У циљу оцене квалитета примене наведеног модела приказани су и подаци оцене нормалних висина при примени GGM EGM96 који је креиран 1996. године од стране Националне агенције за дигиталну обраду слика и картирање (National Imagery and Mapping Agency - NIMA), Центра за космичке летове Националне космичке агенције (Goddard Space Flight Center – GSFC - NASA) и америчког Универзитета Охајо (Ohio State University), који до данас представља најчешће коришћени модел. Из наведеног упоређења следи да се применом модела
GGM05C добијају 50% квалитетније оцене нормалних висина од оних које следе из примене модела EGM96.",

All the solutions meant usage of remove-restore method applying a) detailed gravimetric survey b) appropriate global geopotential model and c) digital terrain model. After determining gravimetric solutions it is necessary to perform their transformation into the system of orthometric i.e. normal heights of high precision leveling network to enable their practical usage in topographic survey. In this paperwork the way of transforming a preliminary gravimetric geoid into the system of orthometric leveling heights of Serbia network is presented.

геодетске референтне основе Србије (АГРОС) при позиционирању тачака пасивне
геодетске основе и тачака детаља премера непокретности. АГРОС омогућује
рутинско позиционирање тачака пасивне геодетске основе и тачака детаља у
реалном времену и центиметарског нивоа тачности. Ови подаци односе се на
геодетски референтни систем реализован станицама АГРОС (геоцентрични). И
поред извесних ограничења, економичност оваквог приступа у великом броју
случајева надмашује традиционалне терестричке технике засноване на мерењима
хоризонталних праваца (углова), дужина и зенитних углова (висинских разлика).
Као основни проблем, који још увек није решен на задовољавајући начин,
препозната је интеграција овако добијених података премера непокретности са
постојећим подацима прикупљеним кроз дуги временски период коришћењем
терестричких техника и израженим у Државном координатном систему Републике
Србије (негеоцентричном). 
Уобичајени начин трансформације између геоцентричног и негеоцентричног геодетског референтног система (тродимензионална седмопараметарска трансформација сличности) може се успешно применити само на ограниченим подручјима због присуства дисторзија (изобличења) у просторним подацима премера непокретности израженим у Државном координатном систему. 
Да би се развио модел трансформације просторних података премера непокретности, обијених применом АГРОС, у Државни координатни систем који би обухватио комплетну државну територију, уочене дисторзије просторних података морају се на одговарајући начин моделирати и отклонити. У оквиру тезе истражене су могућности два приступа при моделирању дисторзија просторних података:
1. Подела подручја трансформације на коначне елементе и 
2. Примена колокације по методи најмањих квадрата.
Развој модела трансформације података премера непокретности добијених применом АГРОС у Државни координатни систем, применом обадва наведена поступка, извршен је на основу скупа од 4401 тачке премера непокретности (узорка просторних података) за које је координате у геоцентричном геодетском референтном систему одредио Републички геодетски завод Србије. Иако је густина  расположивог узорка (приближно 1 тачка на 25 km2 ) недовољна, на основу добијених резултата може се закључити да је применом ових поступака могуће добити довољно тачан и поуздан модел трансформације података премера непокретности добијених применом АГРОС у Државни координатни систем.

геодетске референтне основе Србије (АГРОС) при позиционирању тачака пасивне
геодетске основе и тачака детаља премера непокретности. АГРОС омогућује
рутинско позиционирање тачака пасивне геодетске основе и тачака детаља у
реалном времену и центиметарског нивоа тачности. Ови подаци односе се на
геодетски референтни систем реализован станицама АГРОС (геоцентрични). И
поред извесних ограничења, економичност оваквог приступа у великом броју
случајева надмашује традиционалне терестричке технике засноване на мерењима
хоризонталних праваца (углова), дужина и зенитних углова (висинских разлика).
Као основни проблем, који још увек није решен на задовољавајући начин,
препозната је интеграција овако добијених података премера непокретности са
постојећим подацима прикупљеним кроз дуги временски период коришћењем
терестричких техника и израженим у Државном координатном систему Републике
Србије (негеоцентричном).

AB  - The main task of the surveying is definition, identification, demarcation, measuring and mapping of the boundaries of the natural and artificial objects on the Earth surface. To define the relationship between points, the measurements and the modeling must be done. Development of new technologies made a big changes in phisionomy of surveying. The GPS technology is one of them. Specially, concept of virtual reference station - VRS based on RTK network of permanently developed reference stations is pointed out. In the Republic of Serbia, the network of the permanent stations, named AGROS is projected.
AB  - Premer podrazumeva identifikaciju, dešifraciju, merenje i kartiranje granica prirodnih i veštačkih objekata na zemljinoj površi. Zadatak premera je kreiranje pouzdanog i ažurnog sistema u službi državne administracije i katastra nepokretnosti. Premer integriše terestrička, satelitska, fotogrametrijska i astronomska merenja, upotrebom odgovarajućih matematičkih modela, u cilju definisanja nepoznatih parametara (na primer, horizontalan ili vertikalan položaj tačaka). Savremene merne tehnike sve više osvajaju tržište i nameću potpuno nove standarde u oblasti premera. Danas, značajno mesto zauzima GPS5 tehnologija i koncept VRS6 zasnovan na mreži permanentnih GPS stanica, RTK7 mreži. Na teritoriji Republike Srbije u tom cilju projektovana je i delimično uspostavljena mreža AGROS8, koja pruža nove izazove našim geodetskim stručnjacima.
