Abstract
Purpose. The purpose of this work is to study the possibility of restoring urban traverse networks using high-precision technologies in satellite mode, real-time kinematics. Method. To achieve this goal were involved surveying six teams that were equipped with six receivers of different manufacturers. The observations were made as the "static" and in RTK-mode, and, determining the coordinates of points traverse the network Chernihiv mode performed by permanent RTK networks with different configurations and mount points. Working observations conducted by specialists of the Research Institute of Geodesy and Cartography by the software. After receiving the coordinates of points traverse the network Chernihiv in different systems and known points in the local system was modeled 11 pairs of lines, analysis of changes in the length of which was performed for each coordinate system. Results. The results of this study are: referenсe listed in the state system of coordinates USC-2000 transformation coordinates the network of geocentric spatial rectangular planein Gauss-Kruger in relevant areas; calculated the coordinates of points in SC-42 and SC-63; obtained the mean square error of coordinate definitions with different RTK configurations; analyzed the coordinate value deviations local points traverse the network in different coordinate systems; the analysis of the results of feasibility studies on the use and the possibility of restoring urban traverse networks during the survey and inventory and cadastral works in the settlement with modern RTK technology. Scientific novelty. Analyzing the results of studies established: the high accuracy of the coordinates of receipt of amendments configuration automax of permanent stations and Chernihiv with minor base 10 km distance; average values of deviations between the coordinate values in USC-2000 and the local coordinate system SC-63k and SC-63 are in the range of 0,287 to 0,346 m with an average square error 0,037–0,068 m; the maximum deviation of 0.726 and -0.684 differences in the lengths of lines USC-2000 and SC-63 and between the MSC and SC-42k; distortion of lengths of lines reaches an average of 0,30–0,35 m between the values obtained in the coordinate system USC-2000 and MSC and SC-63; installed error of coordinates of points traverse the network Chernihiv, namely 0,025 m; investigated a discrepancy between the local coordinate system and the SC-42k, which on average is, 0,32 m and corresponding deformation due to network in SC-42 / SC-63 does not provide the required accuracy of conversion options in the local coordinate system; the analysis of study results in the local coordinate system definitions and SC-63 when the error mean square of 0,001 m, indicates the close relationship of law and to establish local coordinate systems for the purpose of minimum distortion Gauss-Kruger and ease of use; the technique of high field of satellite observations using RTK-technology. Practical significance. The results of the studies demonstrated the feasibility of using and the ability to restore existing urban traverse networks using the highly accurate satellite technology kinematics mode in real time. It was established that during the survey and inventory and cadastral works in the settlement using RTK technology provides reliable precision observations. The value of the distortion geodetic network within the settlement area of 100 km2 will be insignificant – within ± 0,03m. Studies have shown that using a coordinate system SC-42 in combination with the satellite technology does not create a significant distortion coordinate territorial definitions and not complicate the process of doing local geodetic work. It should be noted that the City polygonometry points obtained in the local coordinate system and the SC-63 can deliver tangible, to 0.35 m., Distortion geodetic network. So, in the territory of Chernigov local coordinate system creates a local geodetic network and provided its thickening (recovery) RTK-modern technology can be used during the survey and inventory and cadastral.
