| Abstract: | Multipath effect is one of mostly error factors, which infects the quality of GNSS receiver＇ s measurement data. The paper analyses the characteristics of multipath effect and influences to pseudorange and carrier phase of GNSS receiver, and then gives three ways to the analysis of multipath effect and the analysis results of the measurements data to the navigation satellite. Finally, several methods to multipath mitigation are showed. |
