14.11. Limitations of GNSS Surveying

Try these first

1. 1.

   What is signal blockage?

   Hint

   Think of physical obstacles.

2. 2.

   Why is equipment calibration important?

   Hint

   It relates to maintaining performance.

3. 3.

   What is one main cause of GNSS signal blockage?

   • Tall buildings
   • Clear skies
   • Open fields

   Hint

   Consider where you might lose a signal.

4. 4.

   True or False: Atmospheric errors do not affect GNSS accuracy.

   • True
   • False

   Hint

   Think about how weather affects navigation.

5. 5.

   Analyze a scenario where a survey is conducted in a dense forest with GNSS. What limitations might arise, and how would you address them?

   Hint

   Think about visibility and equipment choices.

6. 6.

   Consider the impact of high equipment costs on small surveying firms. What strategies could be employed to mitigate these cost barriers?

   Hint

   Collaborative strategies can reduce individual burdens.
