Challenge Problems
Push your limits with challenges.
Question 1
Suppose a GNSS receiver experiences a positive orbital error causing it to report a position 2 meters to the east of its actual location. How would this impact a real-time construction project?
💡 Hint: Consider how precision affects construction alignment.
Question 2
Discuss how implementing different correction methods can minimize orbital errors during GNSS-based agriculture monitoring. What might be the impacts of not using such corrections?
💡 Hint: Think about the applications of GNSS in agriculture.
