　　Positioning precision of navigation satellite system can be measured by two indicators: the dilution of precision(DOP)and the user equivalent range error(UERE).As the DOP values are only related to the spatial distribution of navigation satellites,the reduction of UERE is the main approach to improve the positioning precision.Equivalent satellite clock(ESC)has been used by Beidou satellite system(BDS)to reduce the UERE and to improve the user's positioning accuracy.
