Q1: What is Total Station?
Ans: A Total Station is an electrical and digitally operated surveying instrument used for measurement and survey work. It combines an Electromagnetic Distance Measuring Instrument (EDM) and an electronic theodolite.
Q2: What is the least Count of Total Station?
Ans: The least count of total station for angle measurement is 1” and for distance measurement is 1mm.
Q3: Define dual-Axis compensation.
Ans: Dual-Axis Compensation ensures reliable horizontal and vertical readings by automatically correcting slight tilts of the instrument.
Q4: Write any three features of total station.
Ans: - ➔ Absolute circle reading
- ➔ High-resolution LCD display
- ➔ Electronic laser distance measurement
Q5: Write three uses of total station.
Ans: - ➔ Distance measurement using infrared signals
- ➔ Angle measurement
- ➔ Co-ordinate determination (X, Y, Z values)
Q6: Name four parts of total station.
Ans: - ➔ Electronic distance meter (EDM)
- ➔ Microprocessor
- ➔ Electronic data collector & storage system
- ➔ Keyboard
Q7: What is EDM?
Ans: EDM (Electronic Distance Meter) is a component in total stations used for measuring distances with high accuracy.
Q8: Define Reflector.
Ans: A reflector in total station functions by reflecting infrared beams, which helps determine angles and distances.
Q9: What are the main functions of total station?
Ans: - ➔ Distance measurement
- ➔ Angle measurement
- ➔ Elevation determination
- ➔ Data processing
Q10: What are the types of total station?
Ans: - ➔ Mechanical Total Stations
- ➔ Robotic Total Stations
- ➔ Prism Total Stations
- ➔ Motorized Total Stations
Q11: Define robotic total station.
Ans: A robotic total station is an advanced instrument that allows remote operation and automatic target tracking.
Q12: Define Prism Total Stations.
Ans: Prism Total Stations use prisms to reflect infrared waves and determine angles and distances.
Q13: Write formula for elevation.
Ans: Elevation of Point B = Elevation of Point A + HI ± L sinφ – HR
Q14: Define electronic book.
Ans: An electronic book is a storage device in a total station where point data can be stored digitally for later use.
Q15: Write three advantages of total station.
Ans: - ➔ High-speed data collection
- ➔ Increased accuracy
- ➔ Easy integration with CAD software
Q16: What is meant by focusing on survey point?
Ans: Focusing on a survey point ensures clear visibility of the target through the telescope by adjusting the focus ring.
Q17: What is optical plummet?
Ans: The optical plummet helps in centering the total station over a ground point accurately.
Q18: How Verifying the Leveling Electronically?
Ans: Leveling is verified electronically using an onboard electronic bubble and adjusting foot screws until centered.
Q19: How Adjusting the Image & Focusing?
Ans: The telescope is aimed at a light background, and the focus knob is adjusted until the image appears sharp.
Q20: Write three Precautions for Using Total Station.
Ans: - ➔ Handle the instrument carefully with both hands.
- ➔ Avoid carrying the total station while mounted on a tripod.
- ➔ Use a charged battery and keep a spare one.
