Carrying out measurements of buildings with RTN GNSS technology in difficult environmental conditions appears to be a major challenge for many surveyors. Achieving the required accuracy of the position of a building structure is often a difficult, and sometimes even an impossible task to perform. This paper presents an innovative solution to increase the reliability of determining the coordinates of building corners, by modernizing the results obtained from the indirect method of measurement of line-line intersection by the socalled half-angle method. Generally speaking, the half-angle method is to verify the angular values in determined points (corners of buildings) from the method of intersection of the base point lines. Optimization of this method involves reducing deformation of a building, which has been determined in real time, taking into account only the classical method of line-line intersection. In order to obtain optimized measurement results, the conversion of the obtained results to the convergent values relative to the most probable coordinates is performed. Based on a detailed comparative and statistical analyses, it can be concluded that the modernized method of line intersection, employed in the RTN GNSS mode with the half-angle method, greatly improves the reliability of determining corners of buildings (X and Y coordinates), as well as provides an exact reflection of the geometric shape of a structure.
