Modern Total Station

It is well known, that requirements to quality of building production quickly grow. It is increases of the common technological level of civil work, reliability, durability, esthetic, adaptability to manufacture of building manufacture increases also.

Engineering-geodetic measurements and engineering-geodetic constructions take special place in the common scheme of civil work. These works begin long before the beginning of construction:
• At carrying out of engineering-geodetic researches,
• Carrying out of projects of constructions in a nature,
• Are a component of technology of civil and erection works during all construction,
• Accompany at quality check of building production and
• Proceed during the operational period at carrying out of supervision over deformations of buildings and constructions if that is demanded with a condition of the project.
Therefore questions of accuracy of carrying out of geodetic works have basic value for finally definition the degree of quality and reliability for buildings and constructions.
At an estimation of reliability and accuracy of measurements the main thing is the choice of the perfect technique of geodetic works and corresponding devices and the equipment, proceeding from the set technology requirements of the project and admissions, With growth of scientific and technical progress and a technological level of construction developed and techniques and devices for carrying out of engineering-geodetic works were improved.
In 60th years of the last century development of geodetic instrument making go on a way of perfection of successfully proved traditional technology. It was based on the physical principles developed basically in the end of XIX century. For last 30 years development of the microelectronics which has become by a symbol of XX century, has begun a new epoch of means and methods of geodetic works
Today the modern geodetic device is the product of high technologies united the last achievements of electronics, exact mechanics, optics and other sciences. And (including with a view of a geodesy) - it is possible to consider count use of satellite navigation of systems safely as new property of a civilization which advantages to the full are not appreciated yet.

In the review tendencies of development of such geodetic systems which can be carried to class of tacheometers, named in English total station.
It is necessary to note, that leading manufacturers of satellite systems, consider Total station as geodetic systems of secondary value, obviously preferring satellite systems of real time (RTK) as to paramount geodetic systems.
So, the first Total station, appeared in January 1999, was focused first of all on users of satellite geodetic systems and as the plan of founders was intended only for addition of opportunities of satellite systems RTK.
