GPS total Station

Area of a science, techniques and the manufacture, that are dealing with developing tools and methods of measurements, and also methods of calculations of mutual and spatial position of objects, parameters of the Earth and its objects and change of these parameters in time.

Disciplines of geodesy

A. Theoretical geodesy, physical geodesy - is engaged in development of theories and methods of definitions of a figure of the Earth (its form and the sizes), an external gravitational field and their changes in time, using astronomic-geodetic, gravitational , satellite and other measurements of high accuracy;
B. Spheroid (al) geodesy, geodesy on the ellipsoid -studies geometry terrestrial ellipsoid, methods of the decision of geodetic problems on its surface and in three-dimensional space, the theory of its display on sphere, and also displays to planes with the purpose of introduction of flat rectangular coordinates
C. Basic geodetic survey - Studies means and methods of precision geodetic measurements, and also methods of mathematical processing of results of measurements with the purpose of construction and fastening on district of scheduled and high-altitude state geodetic networks (these three disciplines traditionally make the maintenance of the global geodesy - geodetic survey(ing), higher geodesy, higher survey(ing)).
The next tools are obligated tools for these measurement: GPS total station
D. Celestial geodesy, satellite geodesy, space geodesy - studies questions of use of supervision of artificial and natural satellites of the Earth for the decision of scientific and scientific and technical problems GEODESY (GPS total station)
E. Topography- studies tools and methods of geodetic measurements with the purpose of display of a terrestrial surface on topographical plans and cards;  
F. Marine geodesy - Solves problems GEODESY within the World ocean;
G. Applied geodesy, engineering geodesy - studies methods of the geodetic measurements which are carried out at researches, designing, construction and operation of engineering constructions, installation of equipment, and also operation of natural resources;
The next tools are obligated tools for these measurement:

• total stations
• theodolites
• combined total station and others;

J. mining geodesy, mine-survey - branch of GEODESY in a mountain science and techniques, is engaged in spatially-geometrical measurements in bowels of the Earth and their display to plans, cards and other documentation. Problems GEODESY solves in close cooperation with astronomy.
