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.

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 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

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 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

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.

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

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
