What is a Theodolite?
General device.
Fields of application of the device.
How theodolite works.
Using the device in the construction
of multi-storey buildings.

3.

In geodesy, along with
levels, such devices as
theodolites are often
used.
With their help, during
general construction
work, specialists
measure horizontal and
vertical angles.

4.

The device is based on a sighting tube, as well as reference
circles (horizontal and vertical). The tube has a certain
magnification and works on the principle of a telescope. It is
mounted on two columns, which, in turn, are fixed on a special
base. It is mounted on a stand called a tribrach.

What a
theodolite is for
is determined
by its accuracy.
The main areas
of use of the
device are:
construction of
industrial
facilities and
not only.

columns are set up first;
the operator also looks
into the microscope
located on the device;
to fix the vertical or
horizontal position of
certain structures, it is
required to fix the
installation angles of
the column in a certain
part of it;
the operator, who looks
into the eyepiece of the
pipe, sees the picture and
the so-called crosshair,
pointing at the control
points;
