Abstract
In this paper, we carried out GPS and BeiDou relative positioning with our developed software using the real data collected in Beijing and Shanghai, respectively, and assessed the accuracy of single epoch baseline solution of the two systems. For short baseline, the relative positioning accuracies of the two systems are basically the same, and the vertical accuracy of the baseline of BeiDou is better than that of GPS. The solved time series errors mainly contain the multipath error and random noise. We used wavelet filtering to extract multipath error according to the frequency characteristics of the random noise and multipath errors. Subsequently, the analysis of GPS and BeiDou multipath was carried out to find the differences between them. Finally, sidereal filtering based on the orbit characteristics of BeiDou was used to eliminate multipath error and improve the relative positioning accuracy. The results showed that the accuracy of relative positioning for short baselines can improve up to 10 % after the multipath error is filtered out.
