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

Description
There was shown that so called “transitive coefficients” A, B, C and D, taking part in making of conditional equations, characterize the geometric figures and can be used to assess the accuracy of net dots position. It is offered to use the recurrent formula to determine the average quadrative point mistakes, received in the result of errors accumulation determining the contiguous linear serifs.

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

Description
The question of coefficients finding under corrections in measured sides excluding the decision of triangular nets is considered for composing of conditional equations with the aim of trilateral nets equalization. The algorithm of coefficients computing by means of differentiation of known formulas of contiguous linear serifs was worked out for nets from triangles.

THE ISSUES OF EQUALIZATION OF GEODETIC CHAIN OF QUADRANGLES
DescriptionThe article examines the development of a planned study on the clearings and roads in builtup 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 – 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

THE COORDINATES OF THE POINTS BACKWARDS THE ANGULAR NOTCH
DescriptionEven 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 wellknown formulas of Gauss and through the calculation of direct geodetic purpose

Description
In this article the question of definition of coordinates 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 coordinates of required points and a numerical example of its realisation is resulted.

HOW TO ESTIMATE THE ACCURACY OF DETERMINING THE COORDINATES IN THE APPROACH OF HANSEN
DescriptionRecently, there have been satellitebased 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 0.30.6 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

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

ON IMPROVING THE ACCURACY OF FILLING GEODETIC NETWORKS OF QUADRANGLES
DescriptionThe 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
