Abstract We calculate the scale parameters of the daily solutions of the IGS second reprocessing campaign with respect to the IGS14 from 7 analysis centers(ACs), analyze the scale parameters using the maximum likelihood method, and investigate the impact of 2 different GNSS antenna phase center correction models on noise characteristics, the long-term rate and seasonal signals of scale parameters. The results show that all the scale parameters exhibit correlated noise that is better represented by a white plus power law noise model. The rates estimated from the scale parameters fluctuate between -0.22 and -0.15 mm/a depending on different ACs. The seasonal signals show the significant annual signals and the weak semi-annual signals. The change of GNSS antenna phase center correction models has a significant effect on the mean scale offset, but there are no obvious variations of noise characteristics, the rate and seasonal signals.
