Challenge Problems

Push your limits with challenges.

Question 1

As a GPS engineer, you must develop a best practice for deploying receivers in urban areas to minimize the multipath effect. What strategies would you propose?

💡 Hint: Consider the environment where signals are transmitted and what surfaces could interfere.

Question 2

Calculate the positional error induced if a satellite's clock is off by 2 microseconds. How does this compare to a standard error from atmospheric delays?

💡 Hint: Use the speed of light as a reference for the calculations.
