Summary: This paper describes our experiences in measuring the GPS-VLBI eccentricity at Medicina (Italy). It has been re-measured yearly during three different terrestrial surveys (2001, 2002 and 2003) and corresponding SINEX files with full variance covariance information were produced. The eccentricity vector connecting the GPS and the VLBI reference points has been measured within slightly different local ground control networks and high accuracy has been sought since the first campaign. The methodology has been refined year after year. We describe the choices that concern stationing, selection of instruments, devices and surveying strategies.
