4.5.1. Satellite Clock Errors

Try these first

1. 1.

   What causes satellite clock errors?

   Hint

   Think about how time is measured in satellites.

2. 2.

   Define atomic clock.

   Hint

   Recall what gives satellites their timekeeping ability.

3. 3.

   What is a primary cause of satellite clock errors?

   • Satellite drift
   • Receiver malfunction
   • Time synchronization issue

   Hint

   Focus on how two systems interact.

4. 4.

   True or False: Atomic clocks in satellites are used for precise timekeeping.

   • True
   • False

   Hint

   Think about what allows GPS to function accurately.

5. 5.

   A satellite clock is found to be running 5 microseconds fast. Calculate the potential error in GPS positioning and discuss how this might affect a precision surveying operation.

   Hint

   Use the speed of light in your calculations.

6. 6.

   Consider a scenario where significant environmental changes occur. How would you ensure that satellite clock errors are minimized for an outdoor surveying project?

   Hint

   Think about the systems in place that help keep clocks accurate.
