PROJECT OF GEODETIC NETWORK FOR GEODETIC MONITORING THE BLACK SEA COASTAL BORDER
The article substantiates the relevance and necessity of designing a special geodetic network to perform deformation monitoring in zones of active seismic activity and the influence of adverse engineering and geological processes and phenomena. The coastline of Bulgaria, where such processes are most pronounced, was chosen as a territorial formation and a zone subject to the active influence of adverse engineering and geological processes and phenomena. It is proposed to use a special satellite network designed in the network version of the construction using GNSS technology as a geodetic justification necessary for geodetic support of deformation monitoring of such a zone of territorial formation. In such a network, it is proposed to place some of the designated points on the coastline, the movement of which will determine the parameters of deformation monitoring, and the other on a relatively stable geological basis. As a result of the assessment of the accuracy of the satellite network project, the mean square errors of the position of the points relative to the origin of the coordinate system and their relative position were obtained. Based on these results, the minimum movements of the satellite network points that can be detected due to mathematical processing between the cycles of geodetic observations are calculated.
