Multipath is one of the main error sources that influence GNSS precise relative positioning. To mitigate multipath error, this paper starts from study of variation characteristics of signal-to-noise ratio (SNR) measurements, and then proposes a satellite selection method based on SNR fluctuation for static relative positioning. Test results indicate that positioning accuracy can be significantly improved by the proposed method.
