DEVELOPMENT OF JOINT APPLICATION TECHNOLOGY SATELLITE AND TRADITIONAL MEANS AND METHODS CONSTRUCTION OF LOCAL GEODESIC NETWORKS

Abstract

The article discusses the main stages and features of the development of technologies for the joint use of satellite and traditional means and methods of building local geodetic networks. It has been established that the urgent task today is the development of the basic principles of joint use of satellite and traditional geodetic measurements in the form of a technological scheme that includes a full range of field and camera work. The scientific novelty of the research carried out lies in the fact that a number of elements of the general technological scheme for the integrated use of satellite and traditional geodetic tools and methods in the construction of local geodetic networks, in particular, coordinate transformations, probabilistic calculations, etc., have been proposed and justified. Algorithms for transforming the coordinates of points and their derivatives from system to system, the transformation matrices of which are expressed in functions of the coordinates of different systems. As a result of the research, new solution algorithms were obtained ypical geodetic problems in functions of the coordinates of different systems: distance reduction, determination of the scale and convergence of meridians in the Gauss-Kruger projection, calculation of slant ranges from coordinate increments, equalization of the spatial trilateration network with the expression of slant ranges in functions of coordinates of different systems, etc. The reliability of the research results is confirmed numerical and natural experiments. The practical significance of the study lies in the fact that the proposed technology will improve the accuracy and reliability of constructing local geodetic networks, reduce the cost of money and time for performing work. It has been proven that increasing the efficiency of building local geodetic networks can be achieved due to the complex use of satellite and traditional means and methods. In this connection, many questions arise regarding the organization and joint use of satellite and traditional means and methods of building local geodetic networks.
