摘要:In this study,Global Positioning System (GPS) simulation is employed to study the effect of five commonly used materials (aluminium,glass,wood,polyvinyl chloride (PVC) and ceramic) on multipath propagation of GPS signals. Based on the results of this study,it is found that multipath signals from panels made of the materials cause increase in probable error values due to errors in the GPS receiver’s pseudorange measurements. The probable errors decrease with increasing distances of the panels from the GPS receiver due to decrease of strength of multipath signals. It is observed that aluminium causes the highest amount of the multipath,resulting in the highest probable errors. This is followed by glass,ceramic,PVC and wood.
