摘要: 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。

关键词: 多路径, 仿真, 时空特性, 量值特性

Abstract: 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 obtained.

Key words: multi-path, simulation, space-time characteristic, value range characteristic
