Robotic total station combined with the principle of linear-angular resection has widely used in the high-speed rail meas-urements, based on the CPⅢhigh-precision track-laying control network ,the precision of the free overlap station can completely satisfy the requirements of high-speed measurement accuracy.In the slab ballastless track plate lofting and orbital plate installation, calculate the farthest lofting distance according to the instrument error parameters on each station under the lofting error do not over-run, to provide the reference for measuring personnel.
