The parameter measurement on station position of electronic total station (ETS) is the key issue of the precise track measurement method based on vehicle borne ETS. The position parameter of ETS can be solved by the equation of the horizontal and vertical deviation of the track central line in the space coordinate system of the car and the multi-point adjustment method under the least square principle. The computer simulation and measurement experiments show that the solving accuracy of ETS position can meet the requirements, that the measurement error of the horizontal and vertical deviation must be less than 1.67 mm, so this method can be applied to measure the absolute position of the track in the actual track adjustment %K 高速铁路 %K 轨道精调 %K 全站仪 %K 平差方法< %K br> %K high-speed railway %K track adjustment %K electronic total station (ETS) %K adjustment method %U http://www.jrse.cn/paper/paperView.aspx?id=paper_318810
