Abstract：The traditional single specular reflection model enables to formulate the basic features of the multipath error,but this model fails to characterize the combined effect of multiple reflection signal in real-istic environment finely.In view of LOS,this paper proposes a new multipath analysis model based on PLLB,deduces an estimating method of multipath error,and researches correlation of pseudo-range mul-tipath error between the epochs and random noise characteristic of dynamic carrier phase multipath error. The results of experiment test show that the pseudo-range multipath has the correlation between the ep-ochs,the paper utilizes this correlation between the epochs for correcting the pseudo-range multipath error to make the double difference pseudo-range error decrease by 52.7%,and due to the random noise charac-teristic,the dynamic carrier phase error will increase.
