The main purpose of this study is the description of the main stages for thickening the geodetic network through satellite measurements in Bara village, Timis County. For geodetic network realization field measurements were taken and then, the ghatered data were proccessed. The measurements were done using the ‚static’ method with 3 double frequency Leica 1200 series receivers L1/L2, in all the 5 settlements of the county: Bara, Lapusnic, Dobresti, Radmanesti and Spata, having as refferece points the GPS national geodetic network: Timisoara, Arad and Faget. For choosing the points that will thickening the geodetic network several criterias were taken into account. That’s why the first stage was to explore the terrain. After this first stage, 20 concrete landmarks were materialized manually after the current rules. This 20 concrete landmarks were equaly distributed in the settlements, 4 in each settlement, 2 at the enterence of the intravilan and 2 at the exit of the intravilan. The next stage was thickening of the geodetic network with other 55 feno landmarks placed in the intravilan of the settlements, usualy at the intersection of the streets, with visibility between them. After materialization of all landmarks, a GPS measurement campaign was made. To this measurements several parameters were taken into account, stationary time at each landmark being the most important. After this static measurements were done, RINNEX data were bought from Cadastral Office and Real Estate Advertising office from Timisoara, Arad and Faget. This RINNEX data were used for processing the raw data resulted from all the landmarks measurements which were post processed using Leica Geo Office software. After the coordinates for the 20 concrete landmarks were obtained through post processing, the other 55 landmarks were determined through ‘radio’ method. For verifying the correctness of the measurements, other 3 existing high order geodetic static signals were determined: Bucina signal, Odaia signal and Lapusnic signal.
