Lysko B. Use of modern technologies for plotting work efficiency increasing

Thesis for the degree of Candidate of Engineering Sciences (Ph. D.) of specialty 05.24.01 – Geodesy, photogrammetry and cartography. – Lviv Polytechnic National University, Ministry of Education and Science of Ukraine, Lviv, 2020. The thesis is devoted to development of modern technologies of complex method applications – the RTN method and electronic tachometers in order to increase efficiency of plotting of construction axes and to a scientific substantiation of the GNSS method application for plotting work providing with necessary regulated accuracy. Based on the method of mathematical planning of the experiment, there have been obtained regressive relations of vector accuracy developed by the RTN method refer to technological parameters. The obtained relation was experimentally proven by studies carried out in a year after the initial ones. The analysis of the obtained mathematical model of technological parameter influence on accuracy of vectors developed by the RTN method showed that the following parameters have the greatest influence on the accuracy of planned plotting works: number of satellites observed by the receiver, HRMS, and HDOP. Algorithms and software for master plan coordinate system to the State Geodetic Coordinate System coordinate transformation have been developed with minimization of random error impact in RTN solutions and possible gross error rejection of coordinates from geodetic bases, especially building restriction line. There have been developed practical recommendations for geodetic plotting base on a construction site to provide the necessary planned accuracy in accordance with the current regulations and significantly simplify geodetic works on construction sites. There have been developed theoretical and experimental substantiation of coordinate transformation method for plotting points by GNSS methods in georeferencing system with topocentric rectangular coordinates. Technological solutions and transformation algorithms were tested during the geodetic support of the construction of buildings united by one technological cycle and the same experimental site.
