Abstract: We found that the variation of horizontal components of the data from solum station is consistent with that of from rock station, but the vertical component is not the same as from rock station when we processed the data of GPS continuous station in Beijing.Combined with the data in 10 IGS stations around Beijing, the data of GPS continuous station in Beijing are processed with GAMIT software, and the possibility to use continuous GPS data from solum station in earthquake research is also discussed.
