On the monitoring model of reference point of VLBI antenna

Abstract

Some insights and analysis are presented concerning the monitoring model of the VLBI (Very Long Baseline Interferometry) antenna, settings of parameters and selection of constraints to the observation equation, which are verified via data simulation analysis to be reasonable and effective. The effects of the number of targets and antenna orientations, the precision of target positioning observations, the observation outliers detection and deletion on the determination precision of antenna parameters are also analyzed, and some preliminary conclusions are given.
