The paper proves the necessity of taking into consideration all peculiarities of unique coordinate system for the realization of potentially high accuracy of modern measuring instrument, especially when processing geodesic measurements made in Moscow, since Bessel ellipsoid is used as a reference ellipsoid instead of more precise Krasovsky ellipsoid. The specific features of geodetic works are considered during the tunnels construction. The way of ellipsoid parameters transformation while creating tunnel base using satellite measuring methods is presented.
