Which is the back side set in total station?
A ‘backsight’ is how you connect to a known point and a known azimuth for orientation. The ‘backsight’ is how you determine the location and orientation of the total station, and therefore the location of all the points that you observe with the total station.
What is backside in surveying?
Back sight (BS) – short for “back sight reading”, the first staff reading taken by the surveyor after the levelling instrument is set up and levelled. B.S is generally taken on the point of known reduced level as on the benchmark or a change point.
What is the purpose of back sight?
backsight-1 A point used to determine the elevation and/or angular orientation of the surveying instrument.
What are the errors in total station?
Total Station Errors
- Horizontal Collimation or Line of Sight Error. Horizontal collimation or line of sight error is when the line of sight is not perpendicular to the tilting axis of the instrument.
- Tilting Axis Error or Tilt Error.
- Vertical Collimation Error or Vertical Index Error.
- Compensator Index Error.
What is the working principle of total station?
The total station consists of a built-in emitter, capable of emitting microwaves and infrared signals. The wavelength of these emitted waves helps in calculating the distance between the points. Here the distance is calculated by multiplying the time taken to cover a certain distance by the velocity.
When total station is sighted to the target which of the operation acts first?
5. When total station is sighted to the target, which of the operation acts first? Explanation: At the time of sighting the instrument towards the target, first step involves the rotation of the instrument’s optical axis from the instrument north in horizontal plane.
What is meant by Total Station in surveying?
A Total Station is a modern surveying instrument that integrates an electronic theodolite with an electronic distance meter. Total Stations use electronic transit theodolites in conjunction with a distance meter to read any slope distance from the instrument to any particular spot.
What is back sight and foresight?
is that backsight is the rear sight of a firearm while foresight is the ability to foresee or prepare wisely for the future.
What is the accuracy of total station?
A typical total station can measure distances up to 1,500 meters (4,900 ft) with an accuracy of about 1.5 millimeters (0.059 in) ± 2 parts per million.
When total station is sighted to the target?
When total station is sighted to the target, which of the operation acts first? Explanation: At the time of sighting the instrument towards the target, first step involves the rotation of the instrument’s optical axis from the instrument north in horizontal plane.
Which of the following is an essential requirement for working with total station?
a. An essential component of the total station is Electronic Distance Measuring (EDM) which is responsible for the distance measurement. The measuring range of the EDM can vary from 2.8km to 4.2km. A typical EDM is capable of measuring the distance with an accuracy ranging between 5mm to 10mm per km of measurement.
What is the total station used for?
Total stations are mainly used by land surveyors and civil engineers, either to record features as in topographic surveying or to set out features (such as roads, houses or boundaries).
What are the advantages of using a total station?
Advantages of Using Total Stations. The following are some of the major advantages of using total station over the conventional surveying instruments: Field work is carried out very fast. Accuracy of measurement is high.
How do I set up and use the total station?
1) Set up the instrument on a sturdy tripod. 2) Turn Total Station until the bubble tube is parallel with 2 of the footscrews, and level the bubble carefully. 3) Turn the Total Station through 90 degrees, and level the bubble using third footscrew carefully. 4) Turn the Total Station back through 90 degrees, and re-level bubble if necessary.
What should I do if my total station is inaccurate?
If the Total Station is classed at 5 second accuracy, then the result would be acceptable. If the result is greater than the accuracy stated on the Total Station then you are best advised to have it adjusted, or repaired, and calibrated by your specialist survey equipment supplier. Total Station Check No. 4. The Vertical Circle Check.
Why does the position of the total station change with angle?
If you have a small angle between the known points, when viewed from the total station, any error that might be present in the readings taken could result in a large error for the position of the total station. This is especially true when only two known points are visible.
