3 cards from this section. Quick, good the night before a test.
What is the role of atomic clocks in GPS?
Think about why clocks are necessary in navigation.
How many satellites are needed to correct clock bias?
Recall the relationship between satellites and positioning accuracy.
What is the main reason for time synchronization in GPS?
Think about the consequences of incorrect timing on location.
True or False: Receive clock bias can lead to inaccurate GPS readings.
Consider the role of a clock in any navigation system.
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?
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.
Reflect on the need for multiple signals to establish a clear reference.
