摘　　要：针对 GPS定位网与地面网重合点坐标不统一的问题 ,提出将重合点坐标作为相关观测值进行平差 ,求出重合点坐标。应用求出的转换参数进行 GPS网非连接点的坐标转换 ,根据最小二乘推估理论导出推估地面网非连接点坐标改正值的数学模型。达到两网统一坐标系统、相互连接的目的。Concerned with the problem that the overlapped points' coordinates of GPS and ground network are not conformtable,this paper raises the way that the overlapped points' coordinates should be adjusted as correlated observations,seeking for confortable coordinates of overlapped points.The coordinates of non connected points of GPS will be converted with the use of getted conversion parameter.According to the theory of least squares adjustment,the mathematical model will be attained refering to the modified coordinates of non connected points of assessed ground network.The aim will be reached that both network are in the same coordinates system and connectet with each other.
