GPS多路径效应是GPS观测中的重要误差源，其严重影响GPS测量成果精度。在研究多路径特点的基础上，从多路径产生原理出发，借助多路径效应信号的函数表达，分析了多路径效应的误差特性，最后通过仿真给出不同情况下的多路径效应影响，得出了多路径效应具有时空特性、量值范围特性的特点。

GPS multi-path effect is an important error source of GPS survey.It seriously influences the GPS measurement accuracy.Based on the research on multi-path characteristic,the error characteristics of the multi-path effect were analyzed by using the principle of generating multi-path from starting and the function of the multi-path signal.Finally,multi-path effect under different circumstances was given by using simulation,and the multi-path effect with the space-time and value range characteristics was ob-tained.
