#### ABOUT A POINT INSERT IN A RIGID FIGURE ON THE BASIS OF LINEAR MEASUREMENTS

abstract 0450901004 issue 45 pp. 47 – 54 30.01.2009 ru 2676
The article describes a condensation of geodetic networks by a point insert in a rigid figure on the basis of linear measurements. Ways of equalising of the received results are considered. The estimation of accuracy of definition of the defined point position is resulted.

#### 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 588
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

#### ON IMPROVING THE ACCURACY OF FILLING GEODETIC NETWORKS OF QUADRANGLES

abstract 1021408009 issue 102 pp. 185 – 192 31.10.2014 ru 740
The article considers the issue of increasing the accuracy of filling geodetic networks of quadrangles with measured by the parties by increasing the number of conditional equations. We have considered the three variants of placement of additionally measured diagonals of the squares. The results improve the accuracy in the determination of coordinates of points within the network, due to these additional measured elements

#### THE COORDINATES OF THE POINTS BACKWARDS THE ANGULAR NOTCH

abstract 1181604090 issue 118 pp. 1387 – 1395 29.04.2016 ru 640
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

#### THE ISSUES OF EQUALIZATION OF GEODETIC CHAIN OF QUADRANGLES

abstract 1141510012 issue 114 pp. 162 – 170 30.12.2015 ru 886
The article examines the development of a planned study on the clearings and roads in built-up and forested areas, as well as for building networks. Most often, it is recommended to use the method without diagonal quadrangles, where in each figure measured all four corners and the length of one of the parties, and in the first and last rectangles â€“ four corners and two sides. The length of the other sides is obtained by computing, previously having leveraged the angles in the quadrilaterals. The disadvantage of this method is the adjustment of such circuits in a simplified manner, namely: the distribution of residuals arising in the augmentation of coordinates fx and fy equally to all augmentation. The article proposes formulas of Gauss for direct angular notches to make the conditional equation of directional angles, deciding which method of least squares, find the amendments to the measured directional angles. Introducing these amendments, I get the coordinates of the desired points of successive angular intersection. As it may be seen from preliminary calculations, the errors resulting from the use of differential corrections in the coordinates are very small and may not have a significant influence on the measurement result

#### 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.

#### TO THE QUESTION OF ASSESSING THE ACCURACY OF GEODETIC NETWORKS OF A QUADRANGLE WITH MEASURED SIDES

abstract 0981404007 issue 98 pp. 94 – 102 30.04.2014 ru 1557
The article presents the weighting function for the points within the geodetic network. The obtained system of equations is solved by the method of least squares. In the result of solving the system of equations we found the original formula for calculation of reverse weights of any point in the geodetic network

#### TO THE QUESTION OF SOLVING THE PROBLEM OF TWO GEODETIC REFERENCE POINTS USING TWO SOURCES

abstract 1171603043 issue 117 pp. 676 – 683 31.03.2016 ru 303
The article examines an important matter of topical problems of the thickening of planned justification from the starting points, for which we have known or predetermined locations using satellite-surveying instruments. The authors present a method of solving the problem of two geodetic reference points using two sources (the approach of the Hansen) by determining the true adjoining corners and converting the problem to the solution of direct angular notches. We have also given a numerical example of the solution and the estimated accuracy of the obtained coordinates of the points P and Q using found valid adjoining corners and edge lengths of the resulting triangles
