On the Effect of Antenna Calibration Errors on Geodetic Estimates

Abstract This paper addresses an approach to assess the impact of phase centre correction errors selected receiving antennas in Polish ASG-Eupos network using GNSS processing strategies such as zero differencing and double differencing. The objective is characterise nature error patterns receiver understand their on derived integrated water vapour geodetic estimates. A semi-analytical for characterising variants applied. Differences up +12 mm between type-mean individual antenna calibrations current models ionosphere-free linear combination are identified repeatable pattern deformations. analyses show that effects tropospheric estimates 8 – which corresponds approx. 1.2 kg/m 2 occur even though only 5 variations were applied pattern. results our analysis a strong correlation with type affect differently. Due complex relationship datum settings, strategy, baseline orientation satellite sky distribution, artefacts must be modelled order achieve better understanding context networks meteorology.
