Abstract The global navigation satellite system (GNSS) coordinate time series is affected by the environmental loading. This study mainly selects the three agencies, namely, the School and Observatory of Earth Sciences (EOST) in France, the German Research Center for Geosciences (GFZ) in Germany, and the International Mass Loading Service (IMLS) in the United States, including 5 types of atmospheric loading (ATML) models, 7 types of hydrological loading (HYDL) models and 5 types of non-tidal oceanic loading (NTOL) models. The classification of these 17 environmental loading models was discussed, and the root mean square (RMS) reduction ratio of the GNSS coordinate time series after environmental loading corrections (ELCs) was used to evaluate the performance differences of various models. In order to correct the nonlinear deformation of the GNSS stations to the greatest extent, based on the above analysis, this study selects the optimal model combination of three environmental loadings as ECMWF_IB + MERRA2 + ECCO1, and then explores its influence on the periodic signals in the GNSS coordinate time series.
