HOW TO ESTIMATE THE ACCURACY OF DETERMINING THE COORDINATES IN THE APPROACH OF HANSEN

abstract 1171603010 issue 117 pp. 192 – 203 31.03.2016 ru 586
Recently, there have been satellite-based methods widely used to determine the coordinates of points, which allow, without mutual visibility between points, to pursue their coordinates. However, in some cases, for example in forests, in urban buildings the application of these methods becomes a problem and it is easier to apply traditional methods. The article describes the case of using the method of calculation of coordinates for "the approach of Hansen" and held to evaluate the accuracy of determining the coordinates of the points. Some studies provide only recommendation guidelines that the most accurate results are obtained when the shape of the building is shaped similar to a square. In our case, on the basis of obtained formulae we had an analysis of the influence of the length of the corresponding base, and its distance from the source side on the accuracy of determination of coordinates of the original points. The conclusion is that the accuracy of determination of coordinates of required points depends on the ratio of the length of the original basis and the baseline. The optimal can be considered the distance equal to 0.3-0.6 of the length of the baseline. The holding data in the study can successfully be used for the drafting of geodetic reference polygonometries moves and thickening of networks

THE COORDINATES OF THE POINTS BACKWARDS THE ANGULAR NOTCH

abstract 1181604090 issue 118 pp. 1387 – 1395 29.04.2016 ru 639
Even with the modern development of geodetic techniques to abandon traditional ways a condensation of planned networks is not possible. Therefore, the article describes the case of determination of coordinates of points using backwards the angular notch and the accuracy of their determination. In the classical methods of solving the backwards the angular notch are calculated coefficients, and get the coordinates of the designated point. The authors propose to use auxiliary angles that will reduce the amount of calculation. In addition, the article gives examples of solutions to well-known formulas of Gauss and through the calculation of direct geodetic purpose

TO DEFINITION OF CO-ORDINATES OF POINTS BY RETURN ANGULAR NOTCHES BY THE METHOD OF CONSECUTIVE APPROXIMATIONS

abstract 0450901005 issue 45 pp. 55 – 61 30.01.2009 ru 2784
In this article the question of definition of co-ordinates of geodetic points for a condensation of planned networks, survey controls and other works by performance of angular measurements on defined points is considered. Initials here are two geodetic points on each defined point. The algorithm of calculation of co-ordinates of required points and a numerical example of its realisation is resulted.
