They are classified according to the accuracy they can achieve, the time needed to obtain fixed solutions and the concept of positioning - number of used receivers, type of measurement, type of GNSS system, etc. One of the most important ways to do this is PPP (Precise Point Positioning) method, primarily because of its simplicity and cost-effectiveness. The paper describes PPP positioning method, its advantages and limitations, as well as the errors that can occur. It also provides an analysis of the performance of PPP method - precision, convergence time, loss of data reception, repeatability of positioning results and accuracy based on three measurement series in duration of 4 hours each, conducted on different days. By comparing the obtained coordinates with reference ones determined by AUSPOS web service, it can be concluded that the difference between these two sets of coordinates varies from 1 cm to 7 cm, while the accuracy of measured height is lower and the difference varies from 7 cm to 20 cm.

Conventional tests and robust methods were applied for detecting outliers. The experimental results indicate that the new approach based on original observations provides higher efficiency of the applied methods than the classical approach for outlier detection in geodetic networks.

Chronology of the development of geodetic reference networks in Serbia / Oleg Odalovic in Survey review, vol 50 n° 359 (March 2018)

This historical summary covers the time from the first organised work in 1855 until today. 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.

Variations of total electron content over Serbia during the increased solar activity period in 2013 and 2014 / Dragan Blagojevic in Geodetski vestnik, vol 60 n° 4 (December 2016)  

Public [article]  inGeodetski vestnik > vol 60 n° 4 (December 2016) . - pp 734 - 744 Titre : Variations of total electron content over Serbia during the increased solar activity period in 2013 and 2014 Type de document : Article/Communication Auteurs : Dragan Blagojevic, Auteur ; Miljana Todorović Drakul, Auteur ; Oleg Odalovic, Auteur ; et al., Auteur Année de publication : 2016 Article en page(s) : pp 734 - 744 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Géodésie spatiale [Termes descripteurs IGN] analyse diachronique [Termes descripteurs IGN] propagation du signal [Termes descripteurs IGN] propagation ionosphérique [Termes descripteurs IGN] retard ionosphèrique [Termes descripteurs IGN] Serbie [Termes descripteurs IGN] signal GPS [Termes descripteurs IGN] teneur totale en électrons [Termes descripteurs IGN] verticale Résumé : (auteur) 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 delay of GPS signals approximately 8.8 m 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 Sun activity during the seasons, and maximal differences of TEC values between the seasons reaching values of 45 TECU, again in the years of high Sun’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.

Suburban design : from "Bedroom communities" to sustainable neighborhoods / Milena Dinić in Geodetski vestnik, vol 60 n° 1 (March - May 2016)  

Public [article]  inGeodetski vestnik > vol 60 n° 1 (March - May 2016) . - pp 98 - 113 Titre : Suburban design : from "Bedroom communities" to sustainable neighborhoods Type de document : Article/Communication Auteurs : Milena Dinić, Auteur ; Petar Mitković, Auteur Année de publication : 2016 Article en page(s) : pp 98 - 113 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Analyse spatiale [Termes descripteurs IGN] banlieue [Termes descripteurs IGN] centre-ville [Termes descripteurs IGN] croissance urbaine [Termes descripteurs IGN] étalement urbain [Termes descripteurs IGN] Serbie Résumé : (Auteur) One of the main issues in the current suburban development is mono-functionality. Suburban formats that mainly function as “bedroom communities” are large housing estates, urban sprawl and suburban satellite housing – former villages surrounding large socialist cities. This paper deals with some urban design principles which encourage unsustainable usage of land at the periphery of cities and cause the “bedroom community” phenomenon. A comparative analysis is performed of three suburban areas where the issue of mono-functionality was/ is present, located within the administrative area of the City of Niš, Serbia: large housing estate in Krive Livade neighbourhood, sprawling neighborhoods Podvinik and Vinik, and former rural settlements Donji Komren and Gornji Komren. The quality of urban design is evaluated using four criteria related to the physical and functional component of urban structure: central urban functions, population densities, public spaces adjacent to central urban functions, and neighborhood traffic. The initial hypothesis of this research is that the mono-functionality represents an unsustainable form of development and that the city needs a polycentric spatial structure. The traditional compact neighborhood with a center, which is pedestrian oriented and has a diversity of uses, is instated as a good quality urban area model.
