应用TEQC和TEQCSPEC软件，得到陆态网络黑龙江省GNSS连续观测站数据多路径误差RMS变化，并分析其特征。结果显示：各测站多路径误差均满足中国地壳运动观测技术规程的要求；设置数据处理时截止高度角为15°，可抑制多路径影响；相邻两天多路径效应重复性较强；相关系数随间隔天数衰减较快；频谱分析结果显示，测站多路经误差主要成分集中在低频段；黑龙江省各测站多路径误差可以归结为随机信号，应从统计意义上进行研究。

Base on TEQC and TEQCSPEC software, we derived CMONOCHeilongjiangProvinceall GNSS continuous observation data Multipath Error RMS Variety, and analysis its property entirely. The results indicate that multipath error of our GNSS data fully meet the China Crustal Movement Observation Technology Rules requirement; When processing the GNSS data, in order to weaken the influence of multipath error, we should set cut-off elevation angle 15°;Multipath errors have strong repeatability adjacent two days; Correlation coefficient reduces quickly with interval days; Spectrum analysis shows that multipath errors mainly focus on low frequency band. It could be boils down to random signal and should be study from the statistical significance.
