Challenge Problems
Push your limits with challenges.
Question 1
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.
💡 Hint: Review DOP calculations to place confidence in estimating changes.
Question 2
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.
💡 Hint: Consider terrain and satellite visibility factors in your response.
