The study evaluates the accuracy of determining coordinates of a corner of a building measured in the RTN GNSS mode (Real Time Network Global Navigation Satellite System) using the method of line-line intersection and having applied the algorithm of vector translation, developed by the author. The performed analysis of accuracy proved a high precision in determining the points subjected to studies. An important factor in the formation of a mean error regarding the position of the corner of a building, having used the algorithm of vector translation, is the assumption of correctness of the reference points, i.e. the so-called base points, determined in the RTN GNSS mode. In this case, the base points take the role of measurement control points. The mean error of the position of the corner of a building, taking into account the innovative solution, is at the level of several centimeters. The study results presented in the article allow to positively evaluate the algorithm of vector translation in terms of accuracy of determining the position of a corner of a building, measured in real time.

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.

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.
