What is total station?
A Total Station is a modern surveying instrument that integrates an electronic theodolite with an electronic distance meter. A theodolite uses a movable telescope to measure angles in both the horizontal and vertical planes.
What are the application of total station?
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.
What is total station and how it works?
A theodolite can be mechanical or electronic. A total station can measure angles and distances electronically and process trigonometrically to give us, at a minimum, position coordinates in space. The horizontal distance, height difference and bearings are calculated automatically.
What are the features of total station?
Capabilities of a Total Station
- Monitors : battery status, signal attenuation, horizontal and vertical axes status, collimation factors.
- Computes coordinates.
- Traverse closure and adjustment.
- Topography reductions.
- Remote object elevation.
- Distance between remote points.
- Inversing.
- Resection.
Why is it called total station?
Initially, Total Station was a proper noun introduced by Hewlett-Packard (HP) to promote its Model 3810A around 1975. Probably because of its tunefulness to the ear, surveyors soon applied the term to all theodolites with a built-in EDM unit and total station became a common noun, written without capital letters.
What is the importance of total station?
A total station is an optical instrument commonly used in construction, surveying and civil engineering. It is useful for measuring horizontal angles, vertical angles and distance — it does this by analyzing the slope between itself and a specific point.
What are the types of total station?
The following are various total station types used in surveying,
- Mechanical Total Stations. Mechanical Total Station.
- Robotic Total Stations. Robotic Total Station.
- Prism Total Stations. Both the mechanical & robotic total stations come under prism models.
- Reflector.
Why it is called total station?
Why is total station important?
Total stations are the primary survey instrument used in mining surveying. A total station is used to record the absolute location of the tunnel walls, ceilings (backs), and floors as the drifts of an underground mine are driven.
What is the main part of total station?
The total station consists of an electronic theodolite, an electronic distance measuring device (EDM), and a microprocessor having a memory unit.
Who introduced total station?
Hewlett-Packard
The total station was first introduced to surveyors under a variety of names, including electronic tacheometer and EDM theodolite. Initially, Total Station was a proper noun introduced by Hewlett-Packard (HP) to promote its Model 3810A around 1975.
Why is a total station called a total station?
What is Total station? What is Total station? A total station is an electronic/optical instrument used in modern surveying and building construction that uses electronic transit theodolite in conjunction with electronic distance meter (EDM).It is also integrated with microprocessor, electronic data collector and storage system.
What are the disadvantages of total station?
Disadvantages of total station: The instrument is more expensive than other traditional survey instruments. Examining and checking the work while surveying can be a problem for the surveyor. Total environment surveying requires additional environmentally friendly surveyors as it is not easy to work with this instrument.
What is a total station theodolite?
A microprocessor within the device takes care of recording, studying, and necessary calculations. Total station or total station theodolite is an electronic or optical instrument used in modern surveying and building construction.
What is the accuracy of a total station?
A typical total station can measure distances with an accuracy of about 1.5 millimeters (0.0049 ft) + 2 parts per million over a distance of up to 1,500 meters (4,900 ft). [2] Reflectorless total stations can measure distances to any object that is reasonably light in color, up to a few hundred meters.
