摘要：Although modern GPS receivers achieve high pseudorange accuracy in line-of-sight (LOS) conditions, multipath remains a dominant source of ranging error in GNSS.
Multipath interference occurs when the user device receives reflected signals in addition to the direct LOS signal. These interference signals are generally reflected from the ground, buildings or trees in terrestrial navigation, while signal reflections from the host-vehicle body are more common in airborne and marine applications.
