14.3. Working Principle of GNSS

Try these first

1. 1.

   What is the main method used for GNSS positioning?

   Hint

   Think about how satellites help locate a position.

2. 2.

   Name one method to measure distance from satellites.

   Hint

   Consider both terms discussed in class.

3. 3.

   What principle does GNSS positioning rely on?

   • Trilateration
   • Triangulation
   • Linear Measurement

   Hint

   Think about how multiple distances are used to find a location.

4. 4.

   True or False: Pseudorange measurements are more accurate than carrier phase measurements.

   • True
   • False

   Hint

   Review the definitions discussed.

5. 5.

   In a GNSS survey, the receiver only gets signals from three satellites. What information will be missing, and how would that impact the positioning?

   Hint

   Consider what each satellite contributes to the geometric calculation.

6. 6.

   How would ambient conditions like heavy cloud cover or urban buildings potentially affect GNSS distance measurements?

   Hint

   Think about the environment's interaction with signal transmission.
