AB  - Surveying instruments have to meet certain specifications in order to provide the necessary accuracy standards for a certain application. The main purpose of testing a used terrestrial laser scanner (TLS) is does an instrument still meets factory accuracy standards or not. This paper outlines the procedures for the investigation of the TLS accuracy in laboratory conditions without high expensive equipment e.g. a calibration track line and a laser interferometer. The test field contains control targets and observation pillars. 3D position of the pillars and the targets are derived from an adjustment of highly precise measurements and they are considered as a true standard compared with the scanned data. A proper statistical model of the data analysis is proposed. In addition to the theoretic model, a particular sample of the highly precise TLS measurements is analyzed.

AB  - Modelling the effects of topographic masses which bear local changes of the gravity field is exceptionally important in the contemporary scientific and practical implementations. The topography effect in this paper is analysed by the digital terrain model of the Republic of Serbia, developed on the basis of the topographic map at the scale of 1:25 000 and by the hypothesis on the equal density of surface layers of the Earth crust. The shortwave characteristic as an impact of the local topography was analysed in parts with different topography for the region of Belgrade and Pal-clan. The gravity field parameters were determined in points of the reference GPS network of the Republic of Serbia and points of the Paracin basis, with the purpose of comparing gravimetric vertical deflections with astro-geodetic vertical deflections.

AB  - Сажетак: Мрежа перманентних станица у Републици Србији је успостављена крајем 2005. године када је и почела да се користи за комерцијалне сврхе. Мрежа је примарно развијена као подршка корисницима у премеру, али такође и као подршка за решавање задатака у области инжењерских радова, развијања геодетских мрежа и навигацији. Због тога и у зависности од захтеване тачности, мрежа је тако замишљена да има три корисничка сервиса. За текуће комерцијалне захтеве, углавном за премер, најчешће је коришћен RTK сервис мреже. Из тог разлога тестирали смо тачност RTK сервиса. Такође, утврдили смо да ли је ова подршка сервиса у складу са пројектованом тачношћу. У ту сврху изведена су експериментална мерења на тачкама са већ познатим координатама и извршена је детаљна анализа добијених резултата. Закључак изведеног експеримента је да RTK сервис мреже перманентних станица пружа тачност координата новоуспостављених тачака у границама од 2-3 cm што је и предвиђено генералним дизајном мреже. Abstract. The permanent station network in the Republic of Serbia was established towards the end of 2005. when it started to be used for commercial purposes. The network was primarily developed as a support to users in surveying, but also as a support for solving problems in the field of engineering works, developing geodetic networks and navigation. Consequently and depending on the required accuracy, the network was conceived to have three customer services. For the current commercial purposes, the RTK service of the network has been most commonly used, mainly for surveying. Therefore, we have tested the accuracy of RTK service. Also we have established whether this service has been realised in compliance with the projected accuracy. For that purpose, experimental measuring has been conducted on the points with already known coordinates and a detailed analysis of the obtained results has been carried out. The conclusion of the conducted experiment is that the RTK service of the permanent station network provides accuracy of coordinates of newly established points within the margins of 2-3 cm, which has been foreseen by the general design of the network.

AB  - Periodic tests of quartz oscillators incorporated in GPS receivers in Serbia are performed in accredited metrological laboratories by the procedure adopted in metrological laboratory ML160. However, receivers of Serbian permanent stations network (AGROS) are permanently mounted on the top of roofs of local cadastral offices, spread along territory of Serbia. They cannot be taken to a metrological laboratory for calibration because of need for constant work. A method for testing their oscillator stability is presented in this paper.
