In order to study the characteristics of BDS carrier phase multipath,the BDS data of different reflective materials and sunny/rainy days are collected.The characteristics of BDS carrier phase multipath in different reflective materials and the sunny/rainy day environ-ment are analyzed using the double differenced observation residual series.The results show that the larger the reflection coefficient of the re-flective material,the larger the multipath effect;the greater the humidity of the same reflective material,the larger the reflection coefficient,and the multipath effect produced is more serious than that in the sunny environment.
