Challenge Problems

Push your limits with challenges.

Question 1

If a GNSS receiver experiences a DOP value of 10, how would this likely affect the accuracy of its positioning? Provide an example based on real-world GNSS applications.

💡 Hint: Think about what type of DOP value is considered acceptable for precision applications.

Question 2

How does atmospheric variability impact the time it takes signals to travel from satellites to a receiver? Estimate how a poorly configured GNSS could lead to positioning inaccuracies.

💡 Hint: Reflect on how different weather conditions alter signal propagation in atmospheric layers.
