14.7. GNSS Surveying Equipment

Try these first

1. 1.

   What does a GNSS receiver do?

   Hint

   Think about what tools are used for navigation.

2. 2.

   What is the role of an antenna in GNSS surveying?

   Hint

   Consider the importance of signal clarity.

3. 3.

   What is the main function of a GNSS receiver?

   • To provide location data
   • To increase satellite signal strength
   • To record data only

   Hint

   Think about your GPS on your phone.

4. 4.

   True or False: An external antenna is not necessary for good GNSS performance.

   • True
   • False

   Hint

   Consider the impact of building interference on signals.

5. 5.

   Suppose a surveyor is using a single-frequency receiver in a rugged area with tall buildings. Discuss the potential issues that may arise and how using a dual-frequency receiver might mitigate these problems.

   Hint

   Consider how more data points help in confusing environments.

6. 6.

   Evaluate the implications of incorrect setups in the base and rover configuration for a large-scale project. What steps can be taken to ensure accurate data collection?

   Hint

   Think about the domino effects of starting off wrong in a survey.
