5.5. Instrument Calibration and Error Management

Try these first

1. 1.

   What is the purpose of calibrating a surveying instrument?

   Hint

   Think about the importance of measurement accuracy in engineering.

2. 2.

   What is one method of calibrating a Total Station?

   Hint

   Recall the alignment checks.

3. 3.

   What does calibration ensure in surveying instruments?

   • A) Increase size
   • B) Ensure accuracy
   • C) Lower costs

   Hint

   Consider what calibration aims to fix.

4. 4.

   True or False: A plummet check is essential for leveling a Total Station.

   • True
   • False

   Hint

   Reflect on what proper alignment means for accuracy.

5. 5.

   You have a Total Station showing consistent errors during measurements across a known baseline. Propose a calibration process to rectify this issue.

   Hint

   Think about the order of checks you typically perform.

6. 6.

   Describe how extreme environmental conditions, like heavy fog, might influence the reliability of GPS data. What steps can be taken to mitigate these effects?

   Hint

   Consider what you know about signal reception and accuracy.
