5.2.8. Limitations of GPS Surveying

Try these first

1. 1.

   What is signal obstruction in GPS surveying?

   Hint

   Think about what might block signals.

2. 2.

   Why is satellite visibility important?

   Hint

   Consider how GPS determines your location.

3. 3.

   What are the consequences of signal obstructions in GPS surveying?

   • They improve accuracy
   • They have no effect
   • They lead to inaccuracies

   Hint

   What do you think happens when a signal can't reach the receiver?

4. 4.

   True or False: Multipath errors can lead to incorrect GPS positioning.

   • True
   • False

   Hint

   Reflecting signals can change how far away things seem.

5. 5.

   You are conducting a survey in a downtown area filled with high-rise buildings. List steps you could take to minimize the impact of signal obstruction on your GPS data collection.

   Hint

   Consider ways to work around tall structures.

6. 6.

   During a project, you encounter multipath errors leading to significant inaccuracies. What methodologies could you apply to improve measurement precision?

   Hint

   Think about technology that helps clean up data signals.
