| 摘 要： | 通过分析多路径误差的产生机理,提出了一些测量中常用的消弱多路径误差的措施,并探讨了多路径误差与温度和气压之间的关系。重点研究固定台站多路径误差的性质,推断出此误差具有时间相关性,多路径误差这种相关性每天会延迟4 min。探讨这些性质有利于消弱多路径误差对GPS地震观测的影响。

| Abstract: | Through the analysis of the mechanism of multi-path error,this paper presents some measures on eliminating multi-path error in measurement.The character of multi-path error at one station under the same condition is mainly studied to infer the temporal correlation of the error.Multipath errors of the correlation would be delayed four minutes a day.Discuss the multi-path error and the relationship with temperature and pressure.This character is helpful for the further research of multi-path error elimination. |
