2013The densification of GPS networks in the national reference system is usually performed at the final stage of computations using a similarity transformation on the projective plain, resulting from the best fit of the new coordinates of common stations of Greek Geodetic Network- new GPS network, to the known values. This procedure leads to dependency or
