Использование поисковых методов для уравнивания и оценки точности элементарных геодезических построений

Abstract

The author provides information about the search methods of adjustment and assessment of the elementary geodetic constructions accuracy on the example of a geodesic triangle under various initial conditions. An algorithm for combining Powell and DSC search methods used to solve the problem posed in the article is given. To equalize the geodesic constructions under consideration by the search method, a program for finding the minimum of the objective function is made, it implements the algorithm described in the article. This program works in the Microsoft Excel format as a macro recorded in the VBA language. Examples of equalization calculations are given. Accuracy assessment of the adjustment results by the search method of the geodesic triangle under different initial conditions is performed. The obtained adjustment results and accuracy estimates are compared with the calculations performed in the NW program by Professor Kougiya V. A. confirmed the correctness of the search method application.
