Basic Features

This paper introduces the basic features and the performance of reflectorless total station. The ranging performance of Sanding KTS750R reflectorless total station is tested through lots of experiments in many ways under the condition of reflectorless, including the reflecting targets with different material property and different color, ranging in different angle of incidence different distance but also on detail point acquisition precision was analyzed., the performance index and application of reflectorless total station was evaluated in different conditions, some useful conclusions were drawn.

When carrying out geodetic work inside production shops or on a construction site, it is necessary to significantly change the focusing of the telescope. Refocusing the telescope can lead to a shift in the sighting axis, and, accordingly, to a decrease in the accuracy of angular measurements. The article presents the results of laboratory studies to determine the horizontal error of collimation and vertical index error of the Leica total station for distances from 2 to 84 m. Therefore, after checking the collimation and vertical index error and automatically taking into account their influence, it is allowed performing geodetic measurements at one position of the vertical circle. In particular, this makes it possible to speed up the execution of fan-shaped trigonometric leveling with short sights, which is performed when observing the settlements of the foundations of industrial buildings and structures.

This paper examines the precision analysis model provided according to the principle of indirect adjustment, to simulate the positioning accuracy at all different conditions including the location of station in total station, the accuracy of angular and side surveying, and compares the accuracy of free-station positioning for only two back-sight points. The results shown that the accuracy of side surveying for instrument has significant influence on positioning accuracy greater than that of angular survey, and the location of stationing points near to the connection line between two back-sight points was benefit for improving the accuracy of positioning.
