Implementation of new methods of processing geodesic measurements using satellite technologies

The purpose of the study, the materials of which are presented in this paper, is to reveal modern approaches to the use of special geodetic networks, based on state geodetic justification. This is especially crucial for the construction of complex objects – roads, bridges, and provides high accuracy of surveying works. The issue is pertinent in terms of the implementation of special geodetic networks. The implementation of new methods of processing geodetic measurements, the use of satellite technologies, and the integration of geographic information systems provide high accuracy and reliability when transferring design solutions to the terrain, which is critical for modern construction projects. According to the current world trends, to create special geodetic networks, it is best to use the GNSS. This method cannot fully replace all existing methods due to the impact of various limitations. The paper proposes to combine the GNSS method and polygonometry. Such a combination significantly reduces measurement time, is labour-saving, economically advantageous, and meets the requirements for the accuracy of creating the corresponding networks. The paper also analyses the world experience on the issue and proposes the use of so-called reference base networks. To increase the accuracy of relative coordinates, an algorithm for the sequence of calculating the points based on the reference base network is proposed, considering errors in the propagation of the satellite signal, the receiver, and errors in determining the coordinates of the specified points. Formulas for calculating the weighted average are proposed, considering the values of differential corrections when determining the coordinates of points of geodetic networks. Thus, in the process of operation of this entire measuring system, it is possible to specify the coordinates of satellites, that is, to link them to the measured bases, thus closing the dimensional chain base – satellite – object – satellite – base. The authors conducted a study that will increase the accuracy of performance and data standardization, simplify the processes of planning, breakdown, and control. This will reduce the occurrence of errors and save resources.
