This article describes a method for transferring the planned coordinates to the installation horizon according to the “vertical design device – GNSS” scheme. This method involves the joint use of a vertical design device and satellite equipment. It is assumed that at least three defined points on the installation horizon will be used. On each of them, coordinate determinations are performed by satellite equipment in real-time kinematics mode. The planned coordinates of one of the three points are transmitted to the installation horizon using a vertical projection device. To ensure the reliability of the results and to exclude the influence of the satellite constellation configuration, the study was conducted in four cycles, equidistant from each other in a time interval. As a result of the study, the main errors in determining the coordinates of points were identified: coordinate shift, angular rotation of the axes of the coordinate grid. The above errors relate to the coordinate definitions of satellite equipment. Ways to compensate for these errors have been proposed for each of them. Separately, it is worth noting the error in calculating the distance between two GNSS points. It was used to control gross errors in coordinate definitions. The data obtained during the study confirm the possibility of using this method for the construction of buildings and structures. The accuracy of transmitting marks in this way is 3 mm.
