14.6.3. Multipath Effects

Try these first

1. 1.

   What are multipath effects in GNSS?

   Hint

   Think about how signals travel before reaching the receiver.

2. 2.

   Give one example of where multipath effects may occur.

   Hint

   Consider environments with tall structures.

3. 3.

   What causes multipath effects in GNSS?

   • Signal timing errors
   • Signal reflections
   • Power errors

   Hint

   Recall how surfaces can alter the path of signals.

4. 4.

   Can multipath effects be minimized?

   • True
   • False

   Hint

   Consider what strategies mitigate errors.

5. 5.

   Consider a GNSS system operating in a city park with tall buildings nearby. How would this environment impact the positioning accuracy, and what steps could be taken to improve the data collection?

   Hint

   Think about the flow of signals and where they might go.

6. 6.

   Analyze how multipath effects could alter the results of a precise engineering survey conducted on a construction site with heavy machinery.

   Hint

   Focus on how the construction site layout affects signal clarity.
