Question 1.
What does DOP stand for?
Show hintHide hint
Think about how positioning accuracy is measured.
Question 2.
Why is satellite geometry important?
Show hintHide hint
Consider the effect of satellite arrangements.
3Question 3.
What does a high DOP indicate?
- High accuracy
- Low accuracy
- Moderate accuracy
Show hintHide hint
Review how geometry affects measurement quality.
4Question 4.
True or False: More satellites improve positioning accuracy.
- True
- False
Show hintHide hint
Consider the geometry of more positions.
Question 5.
Suppose you have a GNSS receiver receiving signals from 5 satellites with a DOP of 10. If two additional satellites join, resulting in better spread, estimate how the DOP could change.
Show hintHide hint
Review DOP calculations to place confidence in estimating changes.
Question 6.
You are tasked with conducting a GNSS survey in a mountainous region. Describe how you would approach the task considering satellite geometry and include possible equipment to assist.
Show hintHide hint
Consider terrain and satellite visibility factors in your response.
