Antenna changes at GNSS reference stations frequently produce discontinuities in their coordinate time series, especially in the height component. These coordinate shifts are mainly caused by changes of carrier-phase multipath effects and also, but usually to a smaller extend, by errors in the antenna phase center corrections. A monitoring method w...
Article
Antenna changes at GNSS reference stations often alter multipath errors which affect carrier-phase observations. As a result, apparent shifts of the antenna position occur. A monitoring method was developed and successfully tested with observation data from Rhineland-Palatinate, which allows modelling these alterations and correcting carrier-phase...
