The accuracy of the continuously operating reference stations’ geodetic network in the Novosibirsk region (CORS VAT) was calculated and evaluated in the state system of coordinates (SC-95) and height (ME-77) forming a fragment of the 19 points of the regional level network. Comparing the results of determining the heights of the network stations using different geoid models was made. A single embodiment of the key conversion system ITRF2005 to geocentric coordinate system and the state of heights was offered. It can be used for constructing the reshaped analog coordinate system SC-95, ME-77 elevation in this area.
