Abstract：The main factors affecting the ranging accuracy of total station on the field baseline are the unsynchronism of air refractive index compensation and the unevenness of the temperature field of the measuring optical path. In order to accurately calibrate the uncertainty of the total station in the field, the 1.2km air environment parameters automatic measurement system was developed, and the dense sensor array was used to automatically measure the environmental parameters along the baseline, the air refractive index real-time compensation total station distance measurement experiment was carried out. The experimental results showed that the ranging error was less than 0.070mm in 7s, and the maximum standard deviation of compensation value was 0.32mm in any 5min. The reliability of the total station ranging results can be effectively analyzed by using the automatic measurement system of environmental parameters.
