The graduation thesis presents a conceptual model of the establishment of the geodetic network, which could be used for simultaneous testing of three different instruments GNSS-RTK. The geodetic network was established in the mountainous area of Jezerca on Krvavec, since the continuously working reference stations GNSS of the national network SIGNAL are located in much lower altitudes. The network comprises six points, established by the classic terrestrial measurements. Moreover, their coordinates were determined globally by several repetitions of the GNSS-RTK method. For the terrestrial measurements, we evaluated influences of meteorological and other parameters on the reduction of the distances. The simulations showed that the greatest influences were due to barometric pressure, temperature as well as the measured zenith distance and distance Sr.
