Accuracy of Determining Buidings' Geometric Characteristics and Structures by Modern Means of Geodetic Measurements

摘要

The article deals with topical issues of determining the accuracy of geometric characteristics of buildings and structures by modern means of geodetic measurements. The method of testing high-precision electronic total stations under production conditions is proposed to evaluate and improve the accuracy of horizontal angle measurements. The paper presents the results of studies on the dependence of spatial coordinates error on the accuracy of measurement and the value of angles and distances using different models of electronic total stations, showing the possibility of determining the coordinates of points on the facade of the building with sufficient accuracy for practice. The necessity of using satellite levelling in solving a number of production problems in different conditions is justified. We have conducted theoretical studies of the accuracy of satellite technology exceedance detection. It is shown that it is possible to determine the exceedances by the method of satellite levelling with high accuracy, allowing to use this method in solving almost any engineering problems, provided that the distances between the observed points are small.
