3.4.6.3.1. Code phase receivers

Try these first

1. 1.

   What type of codes do code phase receivers use?

   Hint

   Recall the types of signals mentioned.

2. 2.

   What is a pseudo-range?

   Hint

   Consider how distance is measured in GNSS.

3. 3.

   What code do code phase receivers primarily use?

   • P-Code
   • C/A-Code
   • Both

   Hint

   Recall the two types of codes used by these receivers.

4. 4.

   True or False: Code phase receivers require prior knowledge of location to function effectively.

   • True
   • False

   Hint

   Think about the 'anywhere-fix' capability.

5. 5.

   How would the performance of a code phase receiver be affected in a densely populated urban area with many tall buildings?

   Hint

   Think about how the environment interacts with satellite signals.

6. 6.

   If a code phase receiver can start calculations with just four satellites, how does adding more satellites enhance its functionality?

   Hint

   Consider the role of satellite positioning in triangulation.
