Abstract	This paper investigates some approaches to improve the accuracy of parameter estimation in geodetic Very Long Baseline Interferometry (VLBI). By analyzing the radio source Sky Coverage (SC) for each antenna, a new approach, the method of condition number is proposed to find out reasonable time ranges for zenith wet delay (ZWD) estimation. The relative accuracy of Earth Orientation Parameters(EOP) is tested after implementing the method of condition number and the result shows that the relative accuracy of EOPs could be improved by ~3% with compared to the equal time range of 20min for ZWD estimation for CONT sessions.
