Abstract: Multipath effects is a factor which reducing the precision of both differential carrier positioning and single point positioning. Most of the existing studies discussed the multipath effects on the differential carrier mode and conducting complex ways to reduce the multipath effects. We study the multipath effect in the GPS system for civil in this topic to conduct a simple and cheap way to reduce the multipath effect. Assumption of using the building models to determine the pattern of the urban and find the satellites which are multipath ones. Through the true distance between the receiver and the satellite we can calculate a common factor to reducing the multipath effect.
