Challenge Problems
Push your limits with advanced challenges
Suppose a GPS receiver reports a position that is 50 meters away due to clock bias. If the receiver was corrected by using data from 4 satellites, what would be the expected accuracy after correction?
💡 Hint: Consider how multiple data points can refine positional estimates.
Critique a scenario where only three satellites transmit signals to a GPS receiver. Discuss the likely outcomes regarding positional accuracy.
💡 Hint: Reflect on the need for multiple signals to establish a clear reference.
