Total stations can now achieve the vast majority of the duties that were historically performed by theodolites or transits. In addition they perform the particular tasks far more reliably and quickly.

The total station possesses 3 main parts namely; the electronic distance measuring component (EDM); the angle measurement component and the processing unit Computer.

These instruments can automatically observe horizontal angles and vertical angles, as well as distances along a slope, from a very simple single create. From these kinds of measurements they can easily , at the media of a button, work out the horizontal as well as vertical distances, elevations and the coordinates associated with the actual points sighted, and show the actual results on a lcd screen. The actual data can be saved onboard or even sent to external systems.

The telescope is definitely an essential part of any total station instrument. It is mounted in between the instrument’s standards, and just after the instrument has been setup level, it can be turned or plunged, so that the axis of sight describes a vertical plane. The axis about which the telescope revolves is known as the horizontal axis. The telescope can also be turned in any azimuthal plane about a vertical line which is called the vertical axis. Being able to both revolve and swivel about these axis allows the operator to aim the instrument in any azimuth, and along any gradient in order to sight the observed points. This is of course essential when measuring angles. The device possesses three reference axes, the sight line, the horizontal and the vertical axes.

Total stations are generally designed with a set of graduated circles which will be mounted in perpendicular planes. The instrument is set up so that the horizontal ring is horizontal. This automatically sets the vertical plane. Current instruments can now perform a simple self leveling action from a nominal level position.

The total station is going to include a lot of pre-programmed tasks that are selectable from the main and sub menus on the LCD screen. Your system will also provide a thorough or perhaps summary help functionality. Prompting the user to accomplish the next required operation. Whilst this will not do away with the requirement for fundamental training. It is a great way of making certain proper operation.

The majority of total stations can carry out complicated calculations on the actual data being measured in ‘real time’ or perhaps at the click of a key after the measurement has bee taken.

Presently there are usually a range of associated items of equipment that are frequently associated with a total station. These would probably include retro leica, tripods along with nail markers and prisms.

Quite a few total stations can now be worked remotely. The operator can set the instrument and then move around with a remote positioning unit. The total station can then be controlled to track until it finds the prism remote device, then document the particular location. The key pad on the remote unit can completely operate the total station and therefore a single man or women could perform a complete survey following set up of the station.

In many cases it will be necessary to be able to re-establish the stations for subsequent surveys. In this kind of case survey nails would probably be utilised in order to form a more long lasting reference. The total station can then be set up over the point for subsequent surveys.
