LIU Dawei HUANG Shengxiang (School of Geodesy and Geomatics,Wuhan University,129 Luoyu Road,Wuhan 430079, China)  
On the basis of a common model of data processing for GPS relative positioning,this paper deduces the cofactor matrix of GPS baseline. According to the theory of GPS control network unity adjustment,by using simulated data,the precision of all points in GPS simulative control network of bridge is estimated by compiling software.
