摘　　要：本文分析了多路径效应产生的原因及其信号特征,利用相同环境下,相邻周期相同时刻的GNSS观测数据多路径误差应有强相关性的特征,采用逐个观测历元差分和卡尔曼滤波相结合的方法来消弱多路径效应的影响,从而提高大型构筑物GNSS监测的成果精度。This paper analyzes the causes of multi path effects and its signal characteristics,in the same environment,multi path error due to the GNSS observation data with the same period of adjacent periods should be characterized by strong correlation,the method used by the influence of epoch difference and Calman filter are combined to weaken the multipath effect,so as to improve the large structures GNSS monitoring the accuracy of the results.
