N2 - In an urban scenario, multipath is one of the main error sources that affects positioning performance. In order to mitigate the impact of multipath on the positioning results, an adaptive weighting model considering multipath is proposed in this paper. In this method, the pseudorange multipath observation model is used to obtain the pseudorange multipath estimation, and the multipath is regarded as a disturbance item added to the observation noise. The normal distribution hypothesis test is performed on the multipath estimation, so as to detect the multipath, and reduce the weight of pseudorange observations containing the multipath. The effectiveness of the proposed method is verified by both static and kinematic tests. The results show that the proposed method can further improve the positioning accuracy and stability of precise point positioning.
