摘　　要：对全站仪中自由设站方法进行了详细剖析 ,指出了现今全站仪中自由设站解求待定点坐标和精度评定的缺陷 ,首次给出了以待定点坐标为虚拟观测值的严密平差解求思路 。The paper in detail analyses the method of free-station position in ETS(electronic total station),points out the lack of unknown point's coordinate solution and precision analysis in currently ETS's free-station program.At first presents the strictness adjustment solution through unknown point coordinates as unreal observation data,and finally some useful results is given through experiment.
