Try these first

1. 1.

   What does the Space Segment consist of?

   Hint

   Think about what helps in providing signals for positioning.

2. 2.

   Name one type of device included in the User Segment?

   Hint

   What devices do you use that can find your location?

3. 3.

   What does the Space Segment consist of?

   • Ground Stations
   • Satellites
   • Receivers

   Hint

   Think of what is found orbiting the Earth.

4. 4.

   True or False: The User Segment includes the satellites.

   • True
   • False

   Hint

   Consider what role GNSS receivers play.

5. 5.

   Consider a GNSS system with seven satellites in view. Describe how many of those satellites a receiver might use for an accurate position and explain why extra satellites are beneficial.

   Hint

   Think about the benefits of redundancy in systems.

6. 6.

   Evaluate the impact on GNSS positioning if the Control Segment fails to synchronize satellite clocks correctly.

   Hint

   Consider what happens when timing is inaccurate.
