The instrument is used to measure sloping distance of object to the instrument, horizontal angles and vertical angles. This Microprocessor unit enables for computation of data collected to further calculate the horizontal distance, coordinates of a point and reduced level of point. Data collected from total station can be downloaded into computer/laptops for further processing of information.
Reflectorless Distance Measurement
Some total stations include not only a conventional infrared distancer that measures to prisms, but also an integrated laser distancer that requires no reflector, giving you the ability to switch between these two options.
Reflectorless distance measurement is particularly beneficial in situations where points are difficult or impossible to access–when positioning pipes or measuring across fences or gorges, for example. Some systems have a co-axial visible red laser dot that can be used to mark targets in connection with the recording of tunnel profiles or indoor work.
Automatic Target Aiming
Total stations that are equipped with an automatic target aiming system make targeting faster and easier. All you have to do is point the telescope at the reflector and push a button that then automatically triggers the fine pointing, angle, and distance measurements, and records all of the values.
This technology makes it possible to carry out fully automatic measurements. After establishing initial contact with the target, automatic target aiming can also be switched to a mode that allows moving targets to be accurately followed and measured independent of the observer.
Describing the position of a point requires two coordinates. Polar coordinates need a line and an angle. Cartesian coordinates need two lines within an orthogonal coordinate system.
The total station measures polar coordinates, which are then recalculated as cartesian coordinates within the given orthogonal system – either within the instrument itself or back at the office.
An angle represents the difference between two directions. Under ideal conditions, the horizontal angle between the two directions leading to the points P1 and P2 is independent of the height difference between those points, provided the telescope always moves in a strictly vertical plane when tilted, whatever its horizontal orientation.
Hi Target Reflector Total Station is designed for measuring of slant distances, horizontal and vertical angles and elevations in topographic and geodetic works, tachometric surveys, as well as for solution of application geodetic tasks. The measurement results can be recorded into the internal memory and transferred to a personal computer interface.
A total station is an electronic/optical instrument used in modern surveying. It is also used by archaeologists to record excavations as well as by police, crime scene investigators, private accident Reconstructionists and insurance companies to take measurements of scenes.
