Because of the increase of water vapor content in the atmosphere or precipitation, the satellite signal prones to multipath effect, which leads to the changes of signal-to-noise ratio(SNR). Therefore, this paper mainly focuses on the correlation among GPS-SNR, precipitation and GPS-PWV. In order to analyze the correlation among GPS-PWV, GPS-SNR and the actual precipitation, this article inverse the foundation GPS atmospheric water vapor (GPS-PWV), and then use the GPS signal to noise ratio(GPS-SNR) for Lomb_Scargle analysis of SNR power spectrum, finally using the actual precipitation data measured by sensors for comparison by using the plate boundary observation program (PBO) GPS network observation data of 62D (doy 153–214). The preliminary results show that the precipitation, GPS-PWV and GPS-SNR has a good relationship in the time distribution. Furthermore, the various parameters of GPS-SNR (A, F, ψ0) rapidly change with the content of GPS-PWV increase or precipitation. © Springer Nature Singapore Pte Ltd. 2017.
