摘　　要：多路径误差,是间接波对直接波的破坏性干涉而引起的站星距离误差。它的大小取决于间接波的强弱和GNSS接收天线抗御间接波的能力。本文以GPS卫星导航定位为例,论述了多路径效应的实际影响。Multipath error is the station-satellite distance error caused by the destructive interference of indirect wave to direct wave.Its size depends on the strength of indirect wave and the ability of GNSS signal receiving antenna to resist the indirect wave.Taking GPS satellite navigation/positioning as an example,this paper discusses the practical impact of multipath effect.

关 键 词：直接波 间接波 多路径效应
