Mongolia, situated around the center of the Asian Continent, is an landlocked country bordering the Russia to the north west and surrounded by the people's Republic of China to the east, west and south. Mongolia has the area of approximately 1, 566,500 .sq km with poprlation of approximately 2,5 million people and athe poprlatjion dinsitay beibg 1.4 persons per sq. km.
The Mongolian GPS network consists of 34 stations and one GPS stations serving approximately 49000-sq.km. The GPS network survey was executed on the existing second order triangulation points to approximately estimate seven parameter datum conversion coefficients between WGS-84 and local system Krassovsky and to establish a primary high accuracy GPS network with ITRF connection in Mongolia.
The GPS network survey project carried out and financed by Monmap Engineering Services Co. Ltd., Ulaanbaatar in cooperation with the Ministry of Defense, Mongolia. The GPS network survey measurement made by Trimble 4000 Ssi receivers and data of the GPS network processed and adjusted by Trimble GPS survey (version 2.3) and Trimnet Plus software
