W pracy przedstawiono wyniki eksperymentu badawczego dotyczącego pomiaru naroży budynków w trybie RTN GNSS. Punkty bazowe zostały wyznaczone w czasie rzeczywistym, natomiast do określenia pierwotnych współrzędnych naroży budynków wykorzystano metodę przecięcia prostych. Wartości uzyskanych współrzędnych zostały poddane dodatkowemu kształtowaniu przy zastosowaniu autorskiego algorytmu zwanego metodą translacji wektorów. Czynności te prowadzą do otrzymania współrzędnych prostokątnych X i Y naroży budynków, które zapewniają wysoką wiarygodność położenia obiektu w terenie i na mapie.

The paper presents the results of a research experiment which involved measuring the corners of building structures in the RTN GNSS mode. The base points were determined in real time, and in order to determine the coordinates of the corners of building structures, the method of line-line intersection was used. The obtained values of the coordinates were modified using the algorithm developed by the author, called the method of vector translation. These activities yielded the Cartesian coordinates X and Y of corners of building structures, which ensured high reliability of the position of an object in the field.

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.

The paper presents an innovative solution which increases the reliability of determining the coordinates of corners of building structures in the RTN GNSS mode. Having performed the surveys of the base points in real time, it is proposed to use the method of line-line intersection, which results in capturing the Cartesian coordinates X, Y of the corners of buildings. The coordinates which were obtained in this way, are subjected to an innovative solution called the method of vectors translation. This method involves modeling the coordinates obtained by the algorithm developed by the author. As a result, we obtain the Cartesian coordinates X and Y of the corners of building structures, the accuracy and reliability of determining which is on a very high level.
