ABSTRACT
In Romania it is used in the work of geodetic, topographic and cadastral local projection system called "Stereographic 1970". And Romania were determined points belonging to continental geodetic networks of global reference systems (WGS84/ETRS89 ) being conducted in several stages National Geodetic Space Network - NGSN consists of coordinate points known European Reference System ETRS89 . Although permanent stations network in Romania is fully functional and permanent stations spread across the country has reached a suitable density , new networks of support through their specificity cannot always develop at a convenient distance to a permanent station in therefore solutions must be found to achieve them. In turn, a network of support geodetic GNSS can be compensated where appropriate, in a different way , as free network partially constrained or constricted . In this paper will be considered and addressed different positioning modes and some variants of calculation, clearing and transformation, presented and compared with each other , yielding interesting findings of interest to improve the positioning of GNSS support networks. The main cases analysed in this paper is Supporting the development of a point of National Geodetic Space Network (NGSN).
