Промежуточные исследования геодезической сети в окрестности карьера “Мурунтау” (Узбекистан)

The article presents the results of GNSS measurements in the vicinity of the “Muruntau” quarry in order to improve the accuracy of the coordinates of the points of the classical geodetic network in 2019-2022. Methods for determining coordinates and methods for compiling topographic maps based on field and aerospace surveys are described. The focus of the work is on the technique of navigational measurements using Trimble R4. The method of thickening the geodetic network based on triangulation points of 2-3 classes is analyzed. An initial basis was calculated to determine the coordinates of points near the quarry based on satellite measurements. An assessment of the accuracy of the starting points was made on the basis of statistical analysis and the least squares method. A digital model of the quarry relief was built on the basis of the refined level surface
