Question 1.
What does signal obstruction refer to in GNSS?
Show hintHide hint
Think about what could block a radio signal.
Question 2.
How many satellites need to be visible for accurate positioning?
Show hintHide hint
Remember the rule of four.
3Question 3.
What is a consequence of signal obstruction?
- Increased accuracy
- Inaccurate positioning
- No effect
Show hintHide hint
Think about whether blocked signals can help or hinder positioning.
4Question 4.
True or False: Atmospheric conditions do not affect GNSS signal accuracy.
- True
- False
Show hintHide hint
Consider if weather can impact other types of signals.
Question 5.
Analyze a GNSS positioning report that shows high DOP values. What might this indicate about the satellite configuration?
Show hintHide hint
Consider what the position of satellites tells you about reception.
Question 6.
Create a scenario where atmospheric disturbances impact a GNSS-based project. How can engineers design their project to mitigate effects?
Show hintHide hint
Think about what steps can be taken before. What tools can help?
