3.4.11.1. Sources of GNSS errors

Try these first

1. 1.

   What is a multipath error?

   Hint

   Think of signals bouncing off walls.

2. 2.

   Define clock error in the context of GNSS.

   Hint

   Consider how accurate satellite clocks are compared to receivers.

3. 3.

   What type of error occurs when GNSS signals bounce off surfaces?

   • Clock Error
   • Multipath Error
   • Ephemeris Error

   Hint

   Consider how light reflects off a mirror.

4. 4.

   True or False: Atmospheric delays can only occur in the ionosphere.

   • True
   • False

   Hint

   Recall the layers of atmosphere.

5. 5.

   A receiver is placed in an urban area surrounded by tall buildings. Discuss how this environment can affect GNSS accuracy and suggest methods to mitigate these effects.

   Hint

   Think about technology that compensates for errors.

6. 6.

   Analyze the implications of solar storms of GNSS operations. What corrective measures can be implemented?

   Hint

   Monitor space weather forecasts regularly.
