GPS multi path can be caused interference between two radio waves which have traveled different length paths between the transmitter and the receiver

GPS multi path caused by reception of signals arrived not only directly from satellites, but reflected or diffracted from local objects.

Multi path results in errors in measurements, affecting the positioning accuracy, since the signal takes a longer path than the direct signal
