Abstract
Highlights •Propose a accurate fitting function descibing the ZTD variation with elevations.•The methodology for obtaining real-time ZTD grid data is simple and requires only GNSS station ZTD data and ERA5 data.•Constraining real-time ppp using RZTDG data can drastically reduce the convergence time of ppp..
