3.3.3. Functions of Total Station

Try these first

1. 1.

   What does a Total Station measure?

   Hint

   Think about the two main components of the instrument.

2. 2.

   What is the function of the microprocessor in a Total Station?

   Hint

   Consider how measurements need to be calculated.

3. 3.

   What is the maximum accuracy of distance measurement in a typical Total Station?

   • 1-2 mm
   • 5-10 mm per km
   • 10-20 mm

   Hint

   Recall what we discussed about EDM capabilities.

4. 4.

   True or False: Total Stations can only measure distances using reflectors.

   • True
   • False

   Hint

   Consider both methods of measurement we discussed.

5. 5.

   A Total Station measures a horizontal angle of 45 degrees and a vertical angle of 30 degrees. If the distance to the target is 100 meters, calculate the coordinates of the target point assuming the Total Station is at the origin.

   Hint

   Use trigonometric conversions for both horizontal distance and elevation.

6. 6.

   In a surveying operation, a Total Station requires atmospheric corrections due to high humidity. If the measured distance is 500 meters, and atmospheric distortion is 2%, calculate the corrected distance.

   Hint

   You must understand how atmospheric conditions impact the specifics of distance measurement.
