The theoretical and experimental studies on multipath effect were carried on. A set of simulating and monitoring system for GPS multipath signals was established, and the continuously two-day-long GPS monitoring data were obtained by means of placing reflecting objects at different heights and distances from the receiver antenna. The improved particle filtering algorithm is the first time being used in the GPS data post-processing. The results indicates that the improved particle filtering algorithm can effectively eliminate the GPS receiver's system noise, and the correlation of continuously two-day-long multipath signals after denoising has the large scale enhancement compared with before denoising.
Keywords:Global Positioning System (GPS); Multipath Effect; Monitoring System
