Efficiency of the RA quasi-geoid model application in cartographic and geodesic works

Data on the application and economic efficiency of the quasi-geoid model of the territory of the Republic of Armenia is presented in the coverage area of the permanently operating reference stations’ network with the application of $GPS$ receivers in design, transfer of designed works into nature and planning works of civil and industrial construction. The effectiveness of work with the application of satellite technology was compared with the traditional methods. As a result of using $GPS$ rover stations, the created maps and plans have higher accuracy and quality compared to traditional methods.
